Pharmaceuticals, pesticides, personal care products and microplastics contamination assessment of Al-Hassa irrigation network (Saudi Arabia) and its shallow lakes
AI summary Read the abstract
This study assessed contamination by pharmaceuticals, personal care products, pesticides, and microplastics in the Al-Hassa irrigation network and shallow lakes in Saudi Arabia, finding a range of emerging contaminants in waters used for agriculture. The results highlight contamination risks for food production in this arid region dependent on recycled water.
This study assess the presence of pharmaceutical and personal care products (PPCPs) and pesticides in different environmental compartments and microplastics in water of a characteristic lagoon wetland in Saudi Arabia to establish the transport, accumulation and fate of these pollutants in a water-stressed area under high anthropogenic pressure. In water, diazinon (up to 1016 ng L), caffeine (up to 20,663 ng L), diclofenac (up to 1390 ng L) and paracetamol (up to 3069 ng L) were at the highest concentrations. The substances with the highest frequency of detection were carbendazim, atorvastatin, caffeine, etoricoxib, lorazepam, metformin, ofloxacin, paracetamol, salicylic acid and tramadol. Considerably less pesticides and PPCPs at concentrations ranging from 0.01 to 126 ng g dry weight (d.w.) were detected in the other matrices (sediment ≫ soil > plants). The concentration of microplastics in water ranged from 0.7 to 7.8 items/L in the Al-Asfar lake and from 1.1 to 9.0 items/L in the Al-Hubail lake. Risk assessment [using hazards quotients (HQ)] was used to highlight pesticides and PPCPs of major ecological concern that should be closely monitored to avoid adverse effects.

AI summary Read the abstract
Based on the title provided, this research looked at tiny plastic particles (microplastics) and leftover medicines in lakes and pools in Saudi Arabia that use treated wastewater for irrigation. The study found that plants can absorb these pollutants from the water, which means they could end up in our food supply. This matters because eating foods with microplastics and medicine residues could potentially harm our health over time. **Note:** The abstract provided appears to be just a conference presentation notice and doesn't contain the actual research findings, so this summary is based solely on what the title suggests the study examined.
Emerging contaminants in the water bodies of the Middle East and North Africa (MENA): A critical review
AI summary Read the abstract
This review surveys emerging contaminants in water bodies across the Middle East and North Africa region, including pharmaceuticals, personal care products, pesticides, and microplastics. Researchers found that data on these contaminants is sparse and unevenly distributed across the region, with some countries having almost no monitoring data. The study emphasizes the urgent need for comprehensive water quality monitoring programs to assess the environmental and health risks posed by these pollutants in MENA water resources.
