Coal burning and agricultural chemicals were the predominant pollution source in the study area.

High concentrations of arsenate (50 and 100 mg As(V) L−1) significantly inhibited all growth parameters and decreased the photochemical efficiency of PSII.

To enhance the understanding of unregulated and unknown HOCs, total organic halogen (TOX) is proposed as a total quantity index for the overall content of HOCs in waters, and has achieved significant progresses. This paper presents a review of TOX analysis from perspectives of detection and pretreatment methods, including the measurement of halide ion (IX) or TOX content by several instruments; separation methods with enrichment based on activated carbon-adsorption, solid-phase extraction, and liquid-liquid extraction, as well as without enrichment based on the subtraction method and IX removal. The relevant fundamentals, operational processes, and key influencing factors are especially concerned. This review should be useful in understanding TOX analysis and the risk of HOCs in waters, and calls for developing more efficient TOX measurement approaches in the future.

The passivated sludge extract had no adverse effects on ryegrass germination and promoted radicle growth. The pot experiment revealed that adding 10% passivated sludge encouraged ryegrass growth while having no appreciable impact on the contents of Cu, Cr, Zn and Pb in the roots and above-ground parts compared to control treatment.

As a new type of pollutant unavoidable produced during human production and living activities, microplastics affect the ecological environment and human health safety. Since microplastics are widely distributed, small-sized microplastics and microfibers may be introduced from ambient air, sampling equipment and laboratory equipment during various monitoring process. Strict quality control measures were required to ensure the accuracy of monitoring results. In order to evaluate the compliance of quality control measures adopted in current researches, eight quality control parameters were statistically summarized by reviewing 30 published researches involving microplastic quality control methods. The results showed that those eight quality control measures could not be fully covered in most studies and uniform standardization of some key quality control measures have not been achieved. It was suggested to develop standardized operational protocols and perform cross-calibration among laboratories.

Group III and V were treated with spirulina orally (1000 mg/Kg) for 3 weeks. Exposure to DEHP elicited marked oxidative stress and associated DNA damage in a dose-dependent manner. The hepatic expression of p53 was also significantly suppressed. Liver and kidney function tests showed marked alterations. Treatment with spirulina efficaciously reversed the adverse effects.

This research aimed to assess the respiratory health of construction workers exposed to silica from tiles, bricks, mortar, and concrete. The study found a positive correlation between construction material dust and fume exposures and workplace seniority. Silica poisoning was dose-dependent on cumulative silica dust or fumes exposure. The average industrial silica particles and emissions BMDLs were 0.68 and 0.30 mg year/m3, respectively. Silica dust and fume BMDLs for silica poisoning were 0.02 mg/m3 and 0.01 mg/m3, respectively. The study concluded that the current exposure levels for silica in China should be re-evaluated, and operational cumulative exposure limits should be established for better prevention of silica poisoning.
