These may affect the environment, but information on their toxicity to benthic biota remains scant. Here, we present results of a 10-day bioassay with the marine nematode <i>Rhabditis</i> (<i>Pellioditis</i>) <i>marina</i> at different loads of barium (0–10 000 ppm nominal concentrations) and cadmium (0–12 ppm) in the range of concentrations reported from drilling-impacted sediments. Barium did not affect the fitness and population development of <i>R</i>. (<i>P</i>.) <i>marina</i> at concentrations up to 300 ppm, but did cause a decrease in population abundance and an increase in development time from concentrations of 400–2000 ppm onwards. Increased mortality occurred at 4800 ppm Ba. For cadmium, LOEC and EC<sub>50</sub> values for total population abundance were 2.95 and 8.82 ppm, respectively. Cd concentrations as low as 2.40 to 2.68 caused a decrease in the abundance of adult nematodes, indicating that assays covering more generations would likely demonstrate yet more pronounced population-level effects. Our results indicate that oil and gas drilling activities may potentially have important implications for the meiobenthos through the toxicity of barium and associated metals like cadmium.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of barium and cadmium on the population development of the marine nematode <i>Rhabditis (Pellioditis) marina</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Environmental pollution; Heavy metals; Barium; Cadmium; Oil drilling;Benthos; Nematodes; Bioassay","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2015-10-28","DateCreate":"2014-06-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000297142900001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.marenvres.2011.07.003"},"refs":null,"anarec":{"AnaID":239271,"PubliDate":2011,"Pagination":"151-159","XtraPublOfAnaID":null,"ISBN":null,"Volume":"72","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43357,"SerRR":"Marine Environmental Research.
