Toxic Pollutant

Carbamate is a highly toxic pollutant for animal, even though this insecticide is biodegradable in nature and in the food chain. The purpose of this research was to find the LC50-96 of carbamate insecticide (Marshall 200 EC) on test organism. The test organism used common carps (Cyprinus carpio L.) with 6-8 cm of length and 5,5-9 g of weight. This study used an experimental method by divided into two steps i.e. preliminary test and acute toxicity (LC50-96) tests.  Preliminary test was done without repetition and twice repetition for acute toxicity. Acute toxicity test data were analyzed by probit analysis. The result showed that LC50-96of carbamate insecticide (Marshal 200 EC) on Cyprinus carpio L. was 1,68 mgL-1.AbstrakPestisida golongan karbamat merupakan sumber pencemar yang sangat toksik bagi hewan, meskipun insektisida go-longan karbamat ini mudah terurai di alam baik pada media air maupun pada organisme dalam rantai makanan. Tujuan penelitian ini ialah mengukur nilai LC50-96 insektisida karbamat (Marshal 200 EC) terhadap hewan uji. Hewan uji yang digunakan pada penelitian ini adalah ikan mas (Cyprinus carpio L.) dengan panjang 6-8 cm dan bobot 5,5-9 g. Metode yang digunakan pada penelitian ini ialah metode eksperimental dengan dua tahapan penelitian, yaitu uji pendahuluan dan uji toksisitas akut (LC50-96). Uji pendahuluan dilakukan tanpa ulangan dan uji toksisitas akut dilakukan ulangan sebanyak dua kali. Data uji toksisitas akut dianalisis dengan analisis probit. Hasil penelitian menunjukkan bahwa nilai LC50-96 insektisida karbamat (Marshal 200 EC) terhadap ikan mas adalah 1,68 mgL-1.

Abstract The use of organophosphate insecticides on commercial vegetable and blueberry farmlands bordering the Nicomekl River, Surrey, B.C., creates the potential for toxic effects on the biota within the drainage ditches and the river itself. To investigate the frequency and magnitude of the toxicity of drainage ditch water and the river water in the vicinity of ditch discharge points, together with the probable cause, water samples were collected from six drainage ditches, and four river locations, at 3-week intervals between June and November 1997. For each of the water samples collected, chronic (7 ± 1 day) survival and reproduction of the cladoceran test organism Ceriodaphnia dubia were compared to that of Nicomekl River headland waters beyond the influence of commercial growing operations. Portions of samples proving to be lethally toxic to the toxicity-test organism were analyzed for organophosphate insecticides (OPs) and subjected to treatment with piperonyl butoxide to ascertain if OPs were the likely contributing cause of the toxicity. Throughout the 6-month monitoring period, a total of 50 ditch water samples and 35 Nicomekl river water samples were collected. None of the river water samples tested produced statistically significant mortality. Two (4%) of the ditch water samples were lethally toxic, with 6- and 7-day median lethal concentrations (LC50s) of 39.9 and 36.5%, respectively. Seven (14%) of the ditch water samples and three (9%) of the river water samples inhibited C. dubia reproduction. A biological toxicity identification evaluation using piperonyl butoxide determined that the toxicant(s) in each of the two ditch water samples which proved lethal to C. dubia were likely metabolically active OP insecti-cide(s). Later chemical analyses on stored portions of the samples revealed trace quantities of chlorpyrifos and/or diazinon. These and other non-measured OPs are believed to have been responsible for the observed lethality. The cause of the inhibited reproduction is for the most part unknown. Providing the 1997 growing season is a typical growing season in terms of OP insecticide use and rainfall, the C. dubia toxicity test results suggest that during the growing season the Nicomekl River and its drainage ditches may periodically be contaminated with OP insecticides at concentrations high enough to sublethally or lethally impact sensitive ditch and river invertebrate fish-food organisms.

Toxicity Analysis

Following regulation, Leachate Treatment Facility (LTF) wasbuilt in Piyungan landfill to reduce its negative impact to the environment. The effluent from this LTF is regularly monitored to check its compliancewith government standard. However, the standard does not fully addressthe effect of combined components in a particular wastewater on livingorganism. Hence, it is necessary to conduct toxicity test to fill this gap. This study was aimed to analyze the acute toxicity status of leachate preand post-treatment from leachate treatment facility of Piyungan Landfill. The method used for the test is Whole Effluent Toxicity (WET) by usingCyprinus carpio as test organism. Acute toxicity test was performed bynon-renewal static method for 96 hours. The result showed that LC50 ofCyprinus carpio are 1,633% and 8,740% for influent and effluent of LTFrespectively. The LTF has reduced the Toxic Unit acute (TUa) ofpretreated leachate with 61,246 in the influent to be 11,442 in the effluent. However, even in the effluent, the leachate is still classified as High AcuteToxicity. It is recommended to improve the performance of LTF to furtherreduce leachate toxicity level to be No Acute Toxicity.
