Prevalence of antibiotic resistance genes in mining-impacted farmland environments

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 289, P. 117651 - 117651

Published: Jan. 1, 2025

Mining activities produce large quantities of tailings and acid mine drainage, which contain varieties heavy metals, thereby affecting the downstream farmland soils crops. Heavy metals could induce antibiotic resistance through co-selection pressure. However, profiles genes (ARGs) in mining-affected crops are still unclear. Here we investigated contents ARG abundances, mobile genetic elements (MGEs), microbial community vegetables from Shangba village (SB), comparison to a nearby reference Taiping (TP). Results showed that SB group, except for Cr, other were all above Chinese Standards. When compared with higher abundances detected vegetables, great proportions resistant sulfonamides, chloramphenicols tetracyclines. In addition, positive correlations found between three classes concentrations (especially Cu, Pb Zn). Spearman's revealed there sul1 total nitrogen, as well tetB/P pH. Additionally, Shannon index values different samples two villages (p < 0.05). Proteobacteria Actinobacteria dominant phyla soil samples. Network analysis suggested multiple genera (belonging Actinobacteria) positively associated many ARGs 0.05), implying they might be potential hosts ARGs. To sum up, this study provided clear evidence mining caused severe pollution farmland, thus posing pressure on persistence affected environments.

Despite Nigeria's immense wealth in water resources, the country faces a significant crisis that is exceptionally difficult to resolve, particularly considering associated public health and security challenges. This review aims expound on complex determinants outcomes of shortage Nigeria focusing more its effects general livelihood stability Nigerians. Using systematic approach, this paper reviews scarcity, causes pollution– including urban activities, agrochemical run-offs, mismanagement – their negative impacts environment Nigeria. A total 305 studies relating pollution were examined study. One point evaluation outlines existing barriers preventing all-inclusive availability clean water, for example, lack appropriate infrastructure inefficient resource management.

Potentially toxic elements in human scalp hair around China’s largest polymetallic rare earth ore mining and smelting area

Environment International, Journal Year: 2023, Volume and Issue: 172, P. 107775 - 107775

Published: Jan. 25, 2023

There is a growing concern about human health of residents living in areas where mining and smelting occur. In order to understand the exposure potentially toxic elements (PTEs), we here identify examine cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb) zinc (Zn) scalp hair area (Bayan Obo, n = 76), (Baotou, 57) reference (Hohhot, 61). total, 194 samples were collected from volunteers (men 87, women 107) aged 5–77 years old three areas. Comparing median PTEs levels between young adults, Ni significantly higher adults while Cr was highest area, no significant difference found for any area. From linear regression model, relationship concentration, log10(PTEs), age found. The concentrations Ni, Cd, Pb lower when compared both addition, Cu Factor analysis (FA) indicated that men (Baotou) Obo), respectively, had different underlying communality suggesting sources these PTEs. Multiple factor quantilized importance gender location combined with hair. results this study indicate people and/or have (Cu, Pb) areas, which may cause adverse effects.

Covalent organic frameworks assisted for food safety analysis

Critical Reviews in Food Science and Nutrition, Journal Year: 2023, Volume and Issue: unknown, P. 1 - 20

Published: July 7, 2023

Food safety incidents threaten human health and life safety. It is an effective method to prevent control the occurrence of food events by enhancing rapid sensitive detection contaminants. Emerging porous materials provide for development efficient stable methods. Covalent organic frameworks (COFs) are favored researchers their highly ordered pore structure, large specific surface area, good structural functional designability. Especially in sensing field, COFs play roles carriers, conductors, quenchers, reporters, have broad application prospects. To better understand COFs-based studies, this review briefly introduces characteristics different analysis, focusing on applications various contaminants (including foodborne pathogens, mycotoxins, pesticides, antibiotics, heavy metals, others). Finally, challenges opportunities discussed facilitate further
