The industrial and domestic waste containing heavy metal contaminate river and the sea. Through bioacumulation process, contaminant was absorbed by aquatic organisms such as fish, shellfish and shrimp. The aim of this research was to identify the influence of fish and shellfish consumption on lead concentration in blood of people who consumed fish and shellfish. Human blood samples were taken as specimens in this research. Maximum level of lead permitted by World Health Organization (WHO) in human blood is 80 mg/100 ml. Samples of human blood, fish, shellfish, and sea water were taken from two locations of fisher groups, i.e. from Sukolilo subdistrict, district of Kenjeran, Surabaya, and from Lobuk village, district of Sumenep, Madura. Lead concentration in the samples were analyzed by AAS (Atomic Absorbent Spectrophotometer) method. Data were subjected for t-test analysis. Results showed that lead concentration in women blood living in Sukolilo (Kenjeran,Surabaya) and Labuk village (Sumenep, Madura) were significantly different, while the mean level of lead in human blood in Sukolilo was higher than that in Labuk village. In Sukolilo, consumption of fish and shellfish had a major contribution to the level of lead in human blood.

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms. Keywords: Physicochemical parameter, wastewater discharge, oil industry, environment, contaminants

Bendiocarb is a broad-spectrum insecticide recommended for malaria control by the World Health Organization (WHO). Still, bendiocarb poses a toxic risk to populations of nontargeted aquatic organisms. Thus, our study was aimed to evaluate the sub-lethal effects of bendiocarb exposure on zebrafish (Danio rerio) embryos by assessing of physiological, developmental, and biochemical parameters. Bendiocarb-induced adverse effects on embryonic development, larval growth, heart rate, changes in phase II detoxifying enzyme glutathione-S-transferase (GST) activity, oxidative stress-related enzyme activities (superoxide dismutase (SOD), catalase (CAT)), and the damage-linked biomarker lipid peroxidation (LPO) in early life stage zebrafish were investigated. Our results highlight that the selected nonlethal concentrations (96 h median lethal concentration in this study was 32.52 mg/L−1) of bendiocarb inflicted adverse effects resulting in embryo deformities (96 h EC50 = 2.30 mg L−1), reduced body- and notochord length (above 0.75 and 0.39 mg L−1 bendiocarb concentrations at 96 hpf, respectively), oxidative stress, and altered heart rate (above 0.4 mg L−1 at 48 hpf) in the studied model system.

Technological advances, coupled with increasing demands by consumers, have led to a drastic increase in plastic production. After serving their purposes, these plastics reach our water bodies as their destination and become ingested by aquatic organisms. This ubiquitous phenomenon has exposed humans to microplastics mostly through the consumption of sea food. This has led the World Health Organization (WHO) to make an urgent call for the assessment of environmental pollution due to microplastics and its effect on human health. This review summarizes studies between 1999 and 2020 in relation to microplastics in aquatic ecosystems and human food products, their potential toxic effects as elicited in animal studies, and policies on their use and disposal. There is a paucity of information on the toxicity mechanisms of microplastics in animal studies, and despite their documented presence in food products, no policy has been in place so far, to monitor and regulates microplastics in commercial foods meant for human consumption. Although there are policies and regulations with respect to plastics, these are only in a few countries and in most instances are not fully implemented due to socioeconomic reasons, so they do not address the problem across the entire life cycle of plastics from production to disposal. More animal research to elucidate pathways and early biomarkers of microplastic toxicity that can easily be detected in humans is needed. This is to create awareness and influence policies that will address this neglected threat to food safety and security.

Abortion is one of the causes of maternal death. The World Health Organization (WHO) estimates that 15-20% of maternal deaths are caused by abortion. Abnormal level of TSH and T4 during pregnancy will be at risk of abortion because the T4 hormone acts to regulate the body's metabolic processes. The purpose of this study to determine the relationship of TSH and T4 levels in the incidence of abortion.         The research design is observational with cross sectional approach which is implemented in regency general hospital of Dr. Rasidin, hospital of Dr. Reksodiwiryo,Bhayangkara hospital, Islam hospital of IbnuSina Padang, and Biomedical Laboratory Faculty of Medicine Andalas University in Padang from September to November 2017. The study population is all pregnant women with gestational age ≤ 20 weeks with diagnosis of abortion. The sample of research 58 respondents by using consecutive sampling technique Examination of TSH and T4 using ELISA method. Test the normality of data by Kolmogorov Smirnov test. Analysis of comparative data by using Pearson correlation test.         The conclusion of this study are the mean serum TSH level is 2.39 ± 1.59 mIU / I and the mean serum T4 level was 8.02 ± 1.43 μg / dl. There is no statistically significant relationship between TSH and T4 levels in aborted event, with p = 0.07 (p> 0,05), with r = -0,23, the relation test is weak, the direction was negative which means more high levels of TSH, the smaller  T4 levels in  mother abortion        The conclusion, the study proves that, there is no significant correlation between TSH and T4 levels in the incidence of abortion.

The Niger-Delta area in Nigeria is rich with rivers, swamps and creeks that are often subject to various forms of pollution. The effect of seasonal variations on the physical and chemical conditions of Warri River was studied in 2015. Temperature and pH values across all seasons fell within the optimum range formost aquatic organisms. Meanwhile, total dissolved solids exceeded the World Health Organization (WHO) permissible limit, especially during the dry season; indicating possible pollution from inorganic salts, organic matter and other dissolved materials in the water. The low dissolved oxygen value recorded was expected due to the high levels of dissolved solids recorded in the river. Lastly, phosphate, nitrate and sulphate concentrations recorded were below the WHO permissible limits. The chemical and biological parameters recorded indicate that the Warri River poses minimal threat to human and animal life.

For the past few decades, environmental pollution is considered a major global problem for public health and this problem has continued to impact aquatic environment. Pharmaceutical discharges are major sources of pollution that poses serious threat to aquatic animals like fish, therefore, this work aimed at evaluating the histological architecture of the gill tissues of Clarias gariepinus on exposed to sub-lethal concentrations of pharmaceutical effluents using standard laboratory procedure. The physicochemical characteristics of the pharmaceutical effluent used revealed varied level of deviations from World Health Organization standard for waste discharge into any categories of water bodies. The histological studies of the sectioned gills of the exposed fish showed varied level of histological alterations which are concentrations dependent. The observed histopathological lesions recorded include infiltration of secondary lamellae, inter-lamellae hyper plastic lesion, and oedema, congestion of the blood vessels, epithelial thickening and lifting, and necrosis of various degrees. All the fish held in the control stock showed inappreciable or no histological degradation and their staining patterns and cellular arrangement remained unaffected and this showed that even low concentration of such effluent is enough to induce physiological imbalances in aquatic organisms. The degrees of all these recorded anomalies were concentration dependent. Therefore, indiscriminate disposal of this effluent is detrimental to aquatic community and to combat this, strict compliance of the laws with total vigilance against illegal discharge of effluent should be enacted and enforced.

According to the World Health Organization, the use of mineral fertilizers and pesticides should be avoided in the cultivation of medicinal plants due to their potential antagonistic actions. Brugmansia spp. is a perennial bush native to South America, but it is also cultivated in Europe, Central America, and Asia due to its ornamental characteristics. Aerial parts of this plant are used in ethnomedicine to alleviate ulcers and pain, as well as to treat abscesses, fungal infection of the skin, and dermatitis. Tropane alkaloids scopolamine and atropine are recognized as active principles of this plant. This study evaluated the applicability of organic agricultural techniques in the cultivation of Brugmansia suaveolens. The influence of different dosages (0-60 tons/ha) of organic fertilizer on the mass productivity of plant shoot as well as their atropine and scopolamine contents were investigated. The average dry matter of leaves (26.54&plusmn;5.12-55.41&plusmn;12.85 g) and stems (26.73&plusmn;8.51-58.60&plusmn;17.62 g) per plant increased with increasingly availability of organic fertilizer (0-60 ton/ha). The same behavior was observed when the contents of the active tropane alkaloids scopolamine (0.72&plusmn;0.03-0.86&plusmn;0.13 mg/g) and atropine (0.79&plusmn;0.03-0.96&plusmn;0.11 mg/g) were monitored by gas chromatography coupled with mass spectrometer. Overall, the treatment at the maximum level tested in this work (60 ton/ha) should be preferred over the other treatments. B. suaveolens could be a potential source of tropane alkaloids for the community of Botucatu city, which is a leading city in Brazil for the cultivation of food products under organic, biodynamic, and agroecology premises.
