“…In general, copper is the most crucial plant growth and development micronutrient. In addition, it helps to increase plants' photosynthesis process and respiration (Angelaki et al 2022;Scott-Fordsmand et al 2022). In this study, copper concentration varies from 8.65 to 18.9 mg/kg with a mean of 13.30 mg/kg.…”

<p>The increasing industrialization and urbanization in recent times has led to a significant increase in heavy metal pollution in soil and sediment. The present study aims to evaluate the heavy metal contamination (HmC) in surface sediments collected from the Kosasthalaiyar River located between latitudes 13°12′03″N and 13°16′34″N and longitudes 80°18′6″E and 80°19′56″E. Ten sampling locations were selected in the study area and samples of surface sediments were collected and analyzed for 16 geochemical and heavy metal parameters, including Silver (Ag), Aluminium (Al), Calcium (Ca), Cadmium (Cd), Chloride, Cobalt (Co), Total Chromium (Cr), Copper (Cu), Mercury (Hg), Manganese (Mn), Molybdenum (Mo), Nickel (Ni), Lead (Pb), Silica (Si), Titanium (Ti), and Zinc (Zn). The study aims to determine the potential environmental hazards of heavy metals in the sediment through calculation of the potential environmental hazard index (RI). Assess the impact of human activities on HmC in the surface sediments using four pollution indices: the Geo-accumulation index (Igeo), the Contaminant factor (CF), the degree of contamination (DC), the potential contamination index (PCI), and the pollution load index (PLI) and Conduct a human health risk assessment (HHRA) of heavy metals in the sediment. The study results will provide insight into the contamination levels and help inform measures for controlling pollution and promoting sustainability in the area.</p>

“…Demographic endpoints can be collected from full life‐cycle experiments that use an integrated approach by tracking life‐history traits of an animal over a full life cycle. Full life‐cycle experiments have been used in many toxicity studies (Jager et al, 2004; Scott‐Fordsmand et al, 2022; Stark & Banks, 2003). With knowledge of the effect of the chemical on demographic endpoints, we can reveal the toxicological sensitivity of different endpoints and quantify the effect of the chemical at the population level by calculating the population growth rate.…”

“…Despite their importance, only a few full life‐cycle experiments have used collembolans. Instead, most full life‐cycle experiments have employed either aquatic organisms (e.g., fish, mollusks, rotifers) or larger terrestrial organisms (e.g., earthworms; Ankley et al, 2005; Hazelton et al, 2012; Santos et al, 2022; Scott‐Fordsmand et al, 2022; Tassou & Schulz, 2011; Zhang et al, 2016).…”

Current standard toxicity tests on nontarget soil invertebrates mainly focus on the endpoints survival and reproduction. Such results are likely insufficient to predict effects at higher organizational levels, for example, the population level. We assessed the effects of exposure to the pesticide teflubenzuron on the collembolan Folsomia candida, by performing a full life‐cycle experiment exposing single individuals via contaminated food (uncontaminated control and 0.2, 0.32, 0.48, 0.72, 1.08, and 1.6 mg/kg dry yeast). Several life‐history traits were considered by following the growth and development of newly hatched individuals over a period of 65 days. We assessed survival, body length, time to first oviposition, cumulative egg production, and hatchability of eggs. A two‐stage model was applied to calculate the population growth rate (λ) combined with elasticity analysis to reveal the relative sensitivity of λ to the effects of teflubenzuron on each life‐history parameter. Body length was the least sensitive life‐history parameter (median effective concentration = 1.10 mg teflubenzuron/kg dry yeast) followed by time to first oviposition (0.96 mg/kg), survival (median lethal concentration = 0.87 mg/kg), cumulative egg production (0.32 mg/kg), and egg hatchability (0.27 mg/kg). Population growth decreased with increasing concentrations of teflubenzuron (λ = 1.162/day in control to 1.005/day in 0.72 mg/kg dry yeast, with populations going extinct at 1.08 and 1.6 mg/kg dry yeast). Elasticity analysis showed that changes in juvenile survival had a greater impact on the population growth rate compared with the other life‐history traits. Our study provides a comprehensive overview of individual‐level effects of long‐term exposure to teflubenzuron and integrates these effects to assess the potential risk to collembolan populations.
