Mercury May Pose Higher Ecological and Human Health Risks than Lead in Vegetables Cultivated on Solid Wastes Dumpsites Soils
Bull Environ Contam Toxicol. 2023 Sep 26;111(4):48. doi: 10.1007/s00128-023-03806-5.ABSTRACTVegetable cultivation on solid wastes dumpsites (SWD) soils is very common in developing countries though unsafe due to heavy metals pollution. In order to evaluate the ecological and human health risks of this practice, Talium triangulare and Lycopersicon esculentum were grown in a greenhouse on soils from two abandoned and active SWD, and control site. The SWD soils were acidic (pH 6.4-6.8), rich in organic matter (10.15%-15.35%) and the heavy metals content patterned Zn > Mn > Hg > Cu > Pb > Ni > Cd. Ecological ...

Degradation of co-applied Atrazine and Fipronil in Phanerochaete Chrysosporium Augmented Biobeds
Bull Environ Contam Toxicol. 2023 Sep 26;111(4):50. doi: 10.1007/s00128-023-03805-6.ABSTRACTWhite rot fungi possess an enzymatic system that is non-specific to any pesticide and can be used for pesticide detoxification in biobeds. The present study evaluated potential of Phanerochaete chrysosporium to degrade co-applied atrazine and fipronil in ash or biochar biomixtures. Five biomixtures were prepared by partially replacing compost in rice straw-compost biomixture (BM) with 10% rice husk ash (RHA), 10% sugarcane bagasse ash (SBA), and 1 and 5% wheat straw biochar (WBC). Results suggested that after 30 days P. chrysosporiu...

On-farm Occurrence of Pharmaceuticals and Their Environmental Hazard: Case Study of a Tropical Dairy farm
Bull Environ Contam Toxicol. 2023 Sep 26;111(4):51. doi: 10.1007/s00128-023-03809-2.ABSTRACTAnimal husbandry wastewaters represent an important source of pharmaceuticals into the environment. This work aimed to evaluate the occurrence of pharmaceuticals and their hazard in wastewater from a model dairy farm from Costa Rica. Among the seven pharmaceuticals detected (acetaminophen, caffeine, carbamazepine, ibuprofen, ketoprofen, risperidone, sulfamethazine), caffeine, ibuprofen and acetaminophen showed the highest concentrations, while caffeine, carbamazepine and risperidone were the most frequently detected compounds. High ...

The Dissipation Kinetics, Residue Level and Dietary Risk of Kresoxim-Methyl in Rosa roxburghii and Soil Based on the QuEChERS Method Coupled with LC-MS/MS
This study aimed to investigate the dissipation, residues and dietary assessment of kresoxim-methyl in the application of Rosa Roxburghii and soil field using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results show that kresoxim-methyl in R. roxburghii samples was extracted by acetonitrile and purified by ethyl enediamine-N-propylsilane (PSA), while kresoxim-methyl in soil samples was extracted by acetonitrile and purified by octadecylsilyl solid phase dispersant (C18). 0.1% formic acid (v/v)-water-methanol solution was used as the mobile phase, LC-MS/MS exhibited a good linearity in the range of 0.001-...
