The contamination levels of 10 main kinds of foodstuffs in 11 provinces and cities were monitored by the national food contamination monitoring system from 2000-2001. About 45 thousand data were obtained in strict quality control. The data indicated that the contamination level of lead was increased in 10 years in meat, eggs, milk-based products especially in preserved eggs, but the contamination levels of arsenic, cadmium and hydrargyrum were not serious by adopting the national standards. Organochlorine pesticides residues (666, DDT) maintained downtrend and organophosphorus pesticides residues met the national associated criteria except methyl parathion in cereals.

Supplemental Operational Guidance for Minimizing Potential Inhalation Doses to Workers and Volunteers at Community Reception Centers and Public Shelters.

In the event of a nuclear explosion in an urban environment, contaminated persons may be directed to Community Reception Centers (CRC) and/or public shelters. This paper is a companion document to a previous paper that addresses the inhalation hazard to workers at a CRC from resuspension of fallout from the evacuees. To limit the inhalation hazard evacuees must be screened to prevent severely contaminated persons from entering a CRC.

This review explores biochar's potential as a sustainable and cost-effective solution for remediating organic pollutants, particularly polycyclic aromatic hydrocarbons (PAHs) and pesticides, in water. Biochar, a carbon-rich material produced from biomass pyrolysis, has demonstrated adsorption efficiencies exceeding 90% under optimal conditions, depending on the feedstock type, pyrolysis temperature, and functionalization. High surface area (up to 1500 m/g), porosity, and modifiable surface functional groups make biochar effective in adsorbing a wide range of contaminants, including toxic metals, organic pollutants, and nutrients.

This study introduces a sustainable biological approach for synthesizing silver nanoparticles (AgNPs) using Conocarpus seeds, aimed at improving the adsorption and photocatalytic degradation of methylene blue (MB) in wastewater treatment. The photocatalytic efficiency of AgNPs, synthesized under varying concentrations of silver nitrate (AgNO) and pH levels, was evaluated, together with the effectiveness of a photocatalytic reactor. The synthesized samples were characterized using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier-transform infrared (FT-IR) spectroscopy, and atomic force microscopy (AFM).

Many contaminants from scattered sources constantly endanger streams that flow through heavily inhabited areas, commercial districts, and industrial hubs. The responses of transplanted mussels in streams in active biomonitoring programs will reflect the dynamics of environmental stream conditions. This study evaluated the untargeted metabolomic and proteomic responses and free radical scavenging activities of transplanted mussels Sinanodonta woodiana in the Winongo Stream at three stations (S1, S2, S3) representing different pollution levels: low (S1), high (S2), and moderate (S3).

Background: Exposure to per- and polyfluoroalkyl substances (PFAS) has been linked with various cancers. Assessment of PFAS in drinking water and cancers can help inform biomonitoring and prevention efforts.
Objective: To screen for incident cancer (2016-2021) and assess associations with PFAS contamination in drinking water in the US.
