1. A biomarker is any substance, structure or process that can be measured in an organism, related to a specific exposure or effect or which can influence the incidence of the effect. Biomarkers can provide valuable information to aid chemical risk assessment processes and are used as investigative tools in both animal and human studies which aim to evaluate carcinogenic hazards and risk. The o...

background: this study aimed to investigate the biosorption of pentachlorophenol on aspergillus niger biomass as a method for removal of pentachlorophenol from aqueous solutions. methods: modified a. niger biomass with naoh was used to absorb the pentachlorophenol. the impacts of various experimental parameters like primary pentachlorophenol concentration, ph of the solution, contact time, and ...

The research presents characteristics of non-carcinogenic and carcinogenic inhalation aquatic chemical risk caused by pollutants atmospheric air drinking water exposure to the health population Arctic city Salekhard. It has been established that risks with chromium, soot formaldehyde as well oral cadmium, beryllium, lead hexavalent chromium correspond upper limit acceptable are subject constant...

A case study of the cancer risk to humans posed by persistent organic pollutants (POPs) in an industrial area of China, which has a long history of contamination from many sources, is presented. Relatively great concentrations of POPs around the chemical industrial parks have the potential to be chronically carcinogenic to local people. Sixteen individual PAHs listed for priory control by the U...

Reservoirs play an important role in living water supply and irrigation of farmlands, thus the water quality is closely related to public health. However, studies regarding human health and ecological risk assessment of polycyclic aromatic hydrocarbons (PAHs) in the waters of reservoirs are very few. In this study, Shitou Koumen Reservoir which supplies drinking water to 8 million people was in...

This study was carried out to assess the human health risk associated with a crude oil spill site in Emohua Local Government Area of Rivers State, Niger Delta. The Total Content and Fraction’s approaches were adopted risk. approach by comparing concentration various contaminants environmental media studied Intervention Values prescribed while Fractions using RBCA Toolkit for Chemical Releases v...

The identification and effective control of pollution sources is essential because heavy metal in agricultural soil associated with food safety public health. Industrial wastewater, waste gas, residues generated from pharmaceutical manufacturing are important pollutants soil, but the research their risk for surrounding inadequate. In this study, typical complex its farmland Hubei Province, Chin...
