The present study, for the first time, provides health awareness about the consumption of pesticide-contaminated leafy vegetables grown in urban backyard garden soils.]]> Mon 31 Jul 2023 15:31:30 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40434 500 μg L−1(acetamiprid). To assess uptake and elimination, shrimp were exposed to a fixed 5 μg L−1 water concentration for eight days (uptake) or four days of exposure followed by four days of depuration (elimination). Neonicotinoid water and tissue concentrations were measured by liquid chromatography-mass spectrometry following solid-phase extraction and QuEChER extraction respectively. The lower toxicity associated with acetamiprid could be associated with lower accumulation in the tissue, with concentrations remaining below 0.01 μg g−1. The activity of acetylcholinesterase, catalase and glutathione S-transferase in abdominal tissues was determined by spectrophotometric assay, with significant sublethal effects detected for all four neonicotinoids. Depuration reduced the tissue concentration of the active ingredient and reduced the activity of oxidative stress enzymes. Given acetamiprid showed no acute toxicity and reduced impact on the enzymatic activity of P. monodon, it may be an appropriate alternative to other neonicotinoids in shrimp producing areas.]]> Mon 08 Aug 2022 13:25:28 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39741 Fri 17 Jun 2022 18:20:04 AEST ]]>
