Bacteria, fungi, viruses, and nematodes are the major causal agents of plant diseases. These phytopathogens are responsible for about 10–40% losses in productivity and quality of food crops and horticultural produce. Although eradication of pathogens is not possible, control of plant diseases has been an area of continuous improvement/research.

This study investigated the regulatory role of Rhodopseudomonas palustris RP11 in alleviating TBBPA-induced harmful effects in soybean seedlings. In this study, the characteristics of growth promotion by strain RP11 were studied by analysing 5-aminolevulinic acid (ALA) and indole-3-acetic acid (IAA) production, as well as phosphorus-solubilizing and potassium-solubilizing ability.

Polycyclic aromatic hydrocarbons (PAHs) and naphthenic acids (NAs) are toxic contaminants of environmental concern found in process water and mature fine tailings, or tailings, from the oil sands industry. BioTiger™, a patented microbial consortium of twelve natural environmental isolates, was found to cometabolically biodegrade the NA hexanoic acid and the PAH phenanthrene in the presence of tailings. Hexanoamide was found to be produced and consumed during cometabolism of hexanoic acid.

Pecan nut is a crop of growing economic importance with a worldwide production around 124,000 tons during the 2017/2018 harvest. Thus, a simple and fast method for the determination of pesticide residues in this crop based on a QuEChERS sample preparation procedure and liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis was developed and validated.

We report on the concentration of heavy metals (cadmium, chromium, cobalt, copper, iron, and lead) in the water and sediment of Lake Greenwood and the streams and creeks that flow into the lake. Our results show heavy metal concentrations well below levels that were reported in 2012.

The MeHg content in the reed wetland soil of Liaohe was studied by the indoor-simulated constant temperature culture method. Under different aerobic and anaerobic conditions, the flooding salinity (CK, 0.5%, 1.0%, 1.5%, 2.0%) changes relationship whether SRB plays a leading role in the formation of MeHg.

A green and efficient sample preparation method using a deep eutectic solvent‐based ultrasounds‐assisted dispersive liquid–liquid microextraction with solidification of the aqueous phase followed by HPLC analysis was developed for preconcentration and determination of heavy metals in environmental samples.

The application of pyrogenic materials in immobilization processes of metalloids represents a burning issue in environmental and waste applications and management. The main objective of this study was to characterize the effect of biomass pretreatment by Cu, Fe and Mg blending and pyrolysis temperature on As sorption efficiency as a model of anionic metalloids from model solutions and As immobilization in old mine soil by pyrogenic materials.

This paper assesses the role of intestinal helminth parasite of Macrobrachium vollenhovenii on host metal accumulation in Lekki lagoon, Lagos, Nigeria. Lead, zinc, copper, chromium and iron concentrations were determined in water, sediment, intestinal parasite, intestine of infected and non-infected prawns. Intestinal nematode parasite Cucullanus sp. was identified. Pb and Cr were not detected in the water and sediment.

Chlorpyrifos (CPF) is a widely used pesticide effective against a large number of target pests, which is used by farmers to protect food crops. Based on earlier epidemiologic reports, which indicate that CPF might interfere with the progesterone signaling pathway and can affect conception, the present study was undertaken to evaluate the binding interaction of CPF with the human progesterone receptor (hPR).

Arsenic has been associated with significant effects on human health. Exposure to inorganic arsenic has been associated with the changes in gene expression. Promoter of CDKN1A antisense DNA damage activated RNA (PANDAR) expression is induced by p53 protein and DNA damage response. Here, we investigated whether the ability of arsenic metabolism in individuals affected the expression of PANDAR, DNA damage, and DNA methylation.
