Summary: Comprehensive monitoring of air and soil in Oman was conducted to understand the sources and fate of organochlorine pesticides. The study found DDTs in agricultural soil samples with a wide range of concentrations and highest levels at locations with intensive agricultural practices. Among the newly enlisted POPs, pentachlorobenzene was detected most frequently in both air and soil samples. The study indicates volatilization processes from soil and the potential cleansing effect of oceanic air on atmospheric OCP levels.

Summary: DDT was widely used in agriculture and disease control, playing a significant role in pest control and saving millions of lives from malaria and other insect-transmitted diseases. However, its stability and persistence in the environment raise concerns about its long-term effects on humans, animals, and the ecosystem. This review focuses on the history, spread, benefits and risks of DDT use, as well as its exposure to animals, humans, and the associated health risks.

Summary: This study assessed the levels, compositions, and distribution of 33 organochlorine pesticides (OCPs) in Greek agricultural soils. DDTs were found to be the major compounds, with the highest concentration. Most samples did not exceed the target values for DDTs, except for one sample from Aegina Island. The majority of analytes had lower concentrations compared to the predicted environmental concentrations, except for the DDE metabolite.

Summary: International Public Health authorities recommend biomonitoring studies to assess chemical exposure in the general population. This study analyzed blood concentrations of various pollutants in a cohort of subjects from Cape Verde and found that 16.7% of the 360 toxic compounds were detected in at least one participant. The study also identified the most frequently detected substances and the factors influencing blood concentrations. This is the first biomonitoring study in Cape Verde and provides useful information for public health measures.

Summary: Previous studies have focused on the direct impact of temperature on the foliar uptake of persistent organic pollutants (POPs), but few studies have explored the indirect impacts of low temperature on foliar uptake. Our study at the treeline on the Tibetan Plateau found that colder climate conditions led to enhanced surface adsorption and slower penetration of dichlorodiphenyltrichloroethanes (DDTs) in leaves, resulting in higher uptake efficiencies and reservoir capacity. The relative humidity, correlated with temperature, also influenced the uptake rates of DDTs.

Summary: This study found high levels of organochlorine pesticides in the former Tekchem Industrial Unit in Salamanca, Mexico, which not only contaminated the soil but also affected the blood samples of school-age children. The results indicate that these pollutants may be dispersed from Tekchem's facilities to the metropolitan area of Salamanca.

Summary: The excessive use of pesticides in Pakistan, a leading country in pesticide use, poses significant threats to human health and the environment. This study reviewed 85 scientific publications and found that Pakistan has high pesticide consumption, with a drastic increase of 1169% in the past two decades. Organochlorines were identified as the most problematic pesticides due to their environmental occurrence and known toxicities. The misuse or overuse of pesticides by farmers, driven by insufficient knowledge about risks, leads to high occupational exposure.

Summary: Arable soils contaminated with persistent and toxic organochlorine pesticides (OCPs) are common due to past agricultural practices. Vegetables, particularly in the Cucurbitaceae family, can accumulate high concentrations of OCPs, including dieldrin, which can lead to chronic exposure for consumers. This study assessed the variability of dieldrin accumulation in fruits of 24 varieties from seven Cucurbitaceae species grown in dieldrin-contaminated soils. Significant interspecific and intraspecific differences were found, indicating that certain varieties could have lower dieldrin concentrations, potentially providing a solution for reducing dieldrin exposure in market vegetables.

Summary: This study found that mink farming in Nova Scotia potentially contributes contaminants such as mercury, polychlorinated biphenyls (PCB), and organochlorine pesticides (OCP) to nearby lakes. Lakes in the catchment area of mink farms had significantly higher mercury and PCB levels compared to downstream lakes and reference lakes. The study also suggests that mink farming may be a source of PCBs in the sediment, along with local agriculture and atmospheric deposition. Additionally, the presence of DDT in lakes near mink farms indicates a possible connection between mink farming and elevated DDT levels, although the source attribution is complicated by mixed land use and historical DDT usage related to forestry. Overall, the study implies a possible association between marine fish meal, fur farms, and aquatic ecosystems in Nova Scotia.

Summary: This study reviews the monitoring of two organochlorine pesticides (DDT and dieldrin) in raptors on a global scale. Monitoring efforts have been biased towards the global north, with most studies conducted in Europe and North America. The limited geographical coverage and narrow species focus may not fully represent the global environments where raptors are found.

Summary: This study aimed to remove reactive blue 19 (RB19) dye from aquatic solutions using tire-derived activated carbon magnetised with Fe3O4 nanoparticles (MAC). The removal efficiency for RB19 was found to be 93.22% under optimal conditions. Isotherm and kinetics studies showed that RB19 adsorption onto MAC followed the Langmuir model and pseudo-second-order model, respectively.

Summary: This study evaluated the efficiency of activated carbon and activated carbon coated with nZVI nanoparticles in removing humic acid from aqueous solutions. The effects of pH, contact time, humic acid concentration, and adsorbent dose on the removal of humic acid were investigated. The results showed that the removal efficiency was influenced by the dose of adsorbent, pH, and humic acid concentration. AC-nZVI exhibited high removal efficiency and had a large surface area and pore volume.

Summary: Microplastics are a emerging pollutant that can enter marine environments like mangrove forests and interfere with the health of the environment and organisms. The concentration of microplastics in sediments is high and fiber and bright color microplastic particles are more common. In addition, mangrove forests exposed to fishing, coastal tourism, urban, and industrial wastewater have higher concentrations of microplastics.

Summary: This study aimed to remove phenol from petrochemical wastewater using the catalyst extracted from pier waste sludge to activate peroxy-monosulfate (PMS). The physical and chemical properties of the catalyst were evaluated, and various operational parameters were tested to optimize phenol removal. The results showed that the catalyst had multiple functional groups on its surface, and the pH factor had a significant impact on the removal efficiency. However, the stability of the catalyst decreased after five cycles.
