Environmental pollution with heavy metals (HMs) is of serious ecological and public health concern worldwide. Mining is one of the main sources of HMs and can impact the environment, species diversity, and human health. This study assessed the value of Spilopelia senegalensis as a biomonitor of environmental contamination with metal(loid)s caused by mining activities. S. senegalensis was collected from a gold mining site and a reference site, and metal(loid)s and biochemical parameters were determined. Lead, cadmium, mercury, vanadium, arsenic, copper, zinc, and iron were significantly increased in the liver, kidney, and lung of S. senegalensis from the mining site. Serum transaminases, alkaline phosphatase, creatinine, and urea were significantly elevated in S. senegalensis from the mining site. Lipid peroxidation and nitric oxide were increased, whereas glutathione and antioxidant enzymes were diminished in the liver and kidney of S. senegalensis from the mining site. In addition, multiple histological alterations were observed in the liver, kidney, and lung of S. senegalensis. In conclusion, mining activities provoke the accumulation of metal(loid)s, oxidative stress, and tissue injury in S. senegalensis. Therefore, S. senegalensis is a valuable biomonitor of environmental pollution caused by mining activities and could be utilized in epidemiological avian studies of human health.

Mineral mining activities with environmental pollution in Nigeria resulted in lead intoxication in humans and livestock. The likelihood of lead contamination of the environment from non-mining sources may exist in Maiduguri, Borno state, Nigeria. The study was carried out to evaluate the bioaccumulation of lead in extensively reared local scavenger chickens-LSC (Gallus gallusdomesticus) in Maiduguri. Two hundred samples each of the liver, kidney, intestine, muscle and blood were tested for lead using standard methods in toxicologic evaluation. There were significant (p<0.05) variations in lead levels in the kidney, liver, muscle, intestine and blood of local scavenger chickens. The highest mean lead level (17.0±12.0µg/kg) was observed in the liver, and the lowest leadlevel (4.0±7.0µg/kg) was in the blood. No significant (p>0.05) sex differences existed in the frequency of lead detection. Mean lead level in the liver of males was significantly (p<0.05) higher than that of females with the highest and lowest mean lead levels occurring in the liver and kidney of male chickens, respectively. The highest lead level detected was 414 µg/kg; in the kidney of a female LSC. It was therefore concluded that environmental pollution with lead may be detected in LSCthat bioaccumulate lead; with the liver having the highest affinity.

Environmental pollution due to heavy metals is a matter of great concern to many scientists and managers worldwide. The threats to human health from heavy metals are primarily associated with the exposure in agriculture production activities. However, a considerable number of technological methods have been used to remove the heavy metals from polluted soils. One of the simplest measures to effectively remove heavy metal contamination is to use both plants and microorganisms, which have been considered "natural materials" or "Bio-Materials" to treat pollutants. This study was conducted on assessing the ability of Trichoderma to absorb heavy metals into the plant. Phytoremediation experiments with Trichoderma were used to remove heavy metals in the soil. Our findings showed that Dracaena Fragrans plants are capable of absorbing heavy metals Cu, Pb, and Zn in soil contaminated with experimental heavy metals.

Abstract Arsenic (As) is one of the toxic metalloids therefore can cause health risk in the consumers through consumption of contaminated food and rice. The current study focused on As speciation in rice, bioavailability, mechanisms and its potential human health risk. For this purpose, rice and soil samples were collected from 16 different districts (non-mining and mining) of Khyber Pakhtunkhwa (Pakistan). Soil physicochemical characteristic such as texture, electrical conductivity (EC), organic matter (OM), pH, iron (Fe) and phosphorus (P) were determined. Total arsenic (AsT) concentrations were analyzed using ICP-MS, while the arsenite (As3+), arsenate (As5+), arsenobetine (BAs), dimethylarsenic (DMA) and monomethyl arsenic (MMA) were determined by HPLC–ICP-MS method. Results showed the highest AsT (0.28 mg/kg) was observed in the rice samples of DI Khan District and lowest (0.06 mg/kg) in Shangla District. However, these findings were found within the permissible limits set by various authorities. Furthermore, results showed higher concentrations of inorganic As (Asi) than organic As (Aso) species in rice. The estimated daily intake (EDI) and incremental lifetime cancer risk (ILTCR) were used to evaluate the potential human health risk for As consumption in rice. Results revealed that the rice samples collected from the district having mining activities had higher value of As (0.28 mg/kg of AsT) as compared to non-mining (0.072 mg/kg of AsT). The highest ILTCR value (0.00196) was observed for rice collected from mining districts. This study revealed that mining activities have great influence on the As contamination of soil and grown rice. This study recommends the soil amendment in districts having mining activities to lower As availability in soil and its bioaccumulation in growing rice that will help to keep lower the potential risk.

As these days there is a lot of effect because of environmental pollution and other factors like work pressure human health problems are increasing to a maximum extent. Technology takes a major role in monitoring the health of a individual. This helps to have a copy of recorded values and this helps in taking immediate steps to cure the condition or a precautions needed. As it important to monitor some parameters of the patient we use some sensors. The bluetooth module helps in collecting data from the sensors and sends it to the mobile through Bluetooth and this data can be uploaded to the cloud using Mobile data. This gives perfect data for the doctors to take a decision and give a suggestion to the patient.
