Abstract Dioxin-like polychlorinated biphenyls (DL-PCBs) are a class of persistent toxic substances with a high potential to accumulate in the soil as an organic pollutant and bioaccumulate in humans. The study determined the level and human health risk of twelve (12) DL-PCBs in soils from mechanic workshops within Nekede mechanic village (NMV), Imo State. In this study, soil samples (0–15 cm depth) were collected at four different sampling points within Nekede mechanic village. At each sampling point, composite samples consisting of 10 sub-samples were collected with pre-cleaned pet bottles using soil auger and were labeled SA, SB, SC, SD. Control sample was taken 500 metres away from the mechanic village where there was no form of auto-mechanic activities. Sample analysis was conducted using Agilent GC 6890N coupled with Agilent MS 5970B to determine the levels of DL-PCBs. The data were analyzed using SPSS version 23. The results revealed that the mean concentration of 12 DL-PCB congeners (Σ12PCBs) in soil ranged from 0.31–16.31 µg kg− 1, which was much higher than that in the control sample (0.006–0.087 µg kg− 1). PCB-126 was the major contributor (58.99%) while the least contributor was PCB-157 (0.0040%) of the Σ12 DL-PCBs TEQ. The estimated LCR (adults 1.29×101, children 4.42×101) and HQs (adults 6.68×102, children 2.29×103) were above the acceptable risk limit (LCR = 10− 4, HQ = 1); indicating a very high adverse effect of DL-PCBs on humans especially children.

Natural And Synthetic

There is a widespread belief on the part of the general public that natural substances are inherently superior to synthetic substances with regard to efficacy and safety in matters related to human health. This question is examined by reviewing the therapeutic use of drugs and herbal medicine preparations, the role of vitamins and nutrients, and the effects of toxic substances. A comparison of the characteristics of natural and synthetic substances within these categories shows a similar range of favorable and unfavorable effects. It is apparent that molecular structure and dose determine the effect of substances on human health, not whether they are of natural or synthetic origin.

Sewage sludge is a serious problem due to the high treatment costs and the risks to environment and human health. Future sludge treatment will be progressively focused on an improved efficiency and environmental sustainability of the process. In this context a survey is given of the most relevant sludge treatment options and separate treatment steps. Special attention is paid to those processes that are simultaneously focused on the elimination of the risks for environment and human health and on the recovery or beneficial use of the valuable compounds in the sludge such as organic carbon compounds, inorganic non-toxic substances, phosphorus and nitrogen containing compounds. Also, a brief assessment is given of the specific future technological developments regarding the various treatment steps. Furthermore, it is discussed how to assess the various pathways which can lead to the required developments. In such an assessment the technical and economic feasibility, the environmental sustainability, the societal acceptance and the implementation route are important factors. The optimal approach also strongly depends on the local and regional situation of concern and the relevant current and future boundary conditions.

Electronic waste, commonly referred as e-waste, is waste generated from discarded waste from an alarming number of electronic components which contains toxic substances affecting human health and the environment across the globe. In India, it is of extreme significance as its huge production uses more electronic materials and thus, dumps a significant amount of  e-waste simultaneously. India is still lacking suitable infrastructure and methods is proper recycling and disposal. This review is an overview of current scenario in the developing countries, India and other countries  depicting the magnitude of environmental and health hazards associated with improper recycling and disposal methods.

Organochlorine Pesticide Residues

This article presents the results of a heath risk assessment in Cidade dos Meninos, an area contaminated with organochlorine pesticide residues located in the county (municipality) of Duque de Caxias, Rio de Janeiro State, Brazil. The Agency for Toxic Substances and Disease Registry (ATSDR) risk assessment methodology was applied. The following organochlorine compounds exceeded the established limits and were considered target pollutants: HCH and its isomers (in eggs, milk, and soil); DDT and its metabolites; trichlorobenzenes; trichlorophenols; dioxins and furans (eggs and soil). For all the substances studied (with the exception of trichlorophenols), the estimated doses exceeded the minimum risk levels for chronically exposed children and adults. According to the ATSDR classification, the area was considered an "urgent public health hazard" because of its high and serious exposure to substances that are dangerous to human health.

The present work addresses the assessment of human health risk from soil contaminated with total petroleum hydrocarbons (TPHs) due to crude oil pollution, with a particular focus on the polycyclic aromatic hydrocarbon (PAH) group of carcinogenic and toxic substances. Given that the measured risk for human health exceeded the accepted level, the study considered an electrochemical remediation method. The laboratory-scale experiments were conducted by using an electric field-based treatment as a possible solution for the remediation of contaminated soil. After 20 days of treatment, while the voltage applied was 15 V (specific voltage of 1 V/cm), the hydrocarbon content was significantly reduced. The parameters measured to determine the overall remediation efficiency were pH, redox potential, ionic strength, soil characteristics, voltage gradient, and zeta potential. The remediation degree observed during the experiments was around 50% for TPHs and 46% for PAHs. The applied remediation method resulted in significant removal efficiency of the tested contaminants from the soil. Consequently, the human health risk assessment for the new degree of contaminants in the soil was achieved. This data demonstrated to what extent the application of the remediation applied technology ensured an acceptable risk under the same exposure conditions for the industrial workers.
