“…In regard to other crustaceans, Nitokra sp showed more tolerance to potassium dichromate than Tiburonella viscana (Abessa & Sousa, 2003) and the harpacticoid copepod Tisbe biminiensis (Araújo-Castro et al, 2009). The measure of sensitivity between each species to potassium dichromate through the LC 50 rates is expressed in Table 4.…”

The present study assesses acute toxicity of non-ionized ammonia and potassium dichromate using the estuarine benthic copepod Nitokra sp from laboratory cultures. Bioassays with non-ionized ammonia sensitivity were carried out, and the mean. Bioassays with non-ionized ammonia sensitivity were carried out, and the mean of LC(I) 50-96h was 1.7 mg.L-1 .-LC(I) 50-96h was 1.7 mg.L-1. Potassium dichromate was used as reference substance in two distinct periods of exposure and the mean LC(I) 50-48h and LC(I) 50-96h values were 55.61 mg.L-1 and 21.70 mg.L-1 , respectively. The organism showed sensitivity to the toxic agents used and good reproducibility of results, indispensable factors for use in ecotoxicological assays.

“…The grain size distribution expressed as % fines (<63 µm), total organic carbon (TOC) and concentrations of Zn, Cd, Pb, Cu, Ni, Co, V, total PAHs and total PCBs were determined by using the appropriate methods, according to the specialized scientific literature (USEPA 8080, 8310, 1999;APHA, 1999). The whole-sediment toxicity test with the amphipod Tiburonella viscana was conducted following the standard protocol (Abessa and Sousa, 2003;Melo and Abessa, 2002). For the second dataset used in the present work, the sediments were collected at five stations distributed around the SSOS diffusers.…”

“…Specimens of T. viscana were collected at Engenho D'Água beach on Ilhabela Island (southeastern Brazil) at low tide using a manual dredge and transported to the laboratory for an acclimation period (48 h). Acute toxicity testing of T. viscana followed the procedures described by Abessa & Sousa (2003), and the protocol NBR 15638 (ABNT, 2021b). Static exposures were set in glass beakers containing 250 mL of test solution (salinity 35 ppt), and 10 animals were exposed/replicate (four replicates) for 48 h under a controlled photoperiod (12:12-h light:dark) and temperature (25 °C).…”

Cigarette butts (CBs) are the most common type of beach litter worldwide and contain a complex mixture of chemicals. Given the recent interest in this emerging problem, it is important to assess the toxicity of CB leachates to a range of species from different regions, sensitivities, and ecological traits. We evaluated the waterborne toxicity of smoked CB to tropical invertebrates. Leachates were prepared in the laboratory and characterized for trace elements (Mn, Fe, Co, Ni, Cu, Zn, As, Cd, and Pb), ammonia nitrogen, and polycyclic aromatic hydrocarbons. Then a set of toxicity tests with marine invertebrates was performed as follows: the brine shrimp Artemia sp. (nontoxic); the amphipod Tiburonella viscana (median lethal concentration [LC50] of 0.038 CB/L); the tanaid Monokalliapseudes schubarti (LC50 of 0.126 CB/L); the copepods Tisbe biminiensis (median effect concentration [EC50] of 0.038 CB/L) and Nitokra sp. (EC50 of 0.009 CB/L); pluteus stage larvae of the sea urchin Echinometra lucunter (EC50 of 0.152 CB/L); the sand dollar Mellita quinquiesperforata (EC50 of 0.054 CB/L); and D‐stage larvae of the mussel Perna perna (EC50 of 0.005 CB/L). The predicted no‐effect concentration was estimated using species sensitivity distribution, producing a 5th percentile hazard concentration of 0.015 CB/L. This preliminary threshold allowed us to estimate the potential impact of a single CB to 67 L of seawater via leaching, contributing to the advancement of knowledge regarding the contamination, toxicity, and ecological risks of cigarette waste.
