Organochlorine Pesticides in Freshwater Fish from the Zagreb Area

Abstract

Organochlorine Pesticides in Freshwater Fish from the Zagreb AreaThe aim of this study was to determine the level of organochlorine pesticides in freshwater fish from the Zagreb area, Croatia. The study included 215 freshwater fish samples from three sites: the Sava River, Lake Jarun, and five fishponds from the Zagreb surroundings. Organochlorine pesticides DDT and derivates, HCH, HCB, lindane, aldrin, dieldrin, endrin, heptachlor with epoxide, and methoxychlor were determined using the GC-ECD method. The determined amounts of organochlorine pesticides were within allowed concentration limits in all analysed fish samples. Median values ranged from below the detection limit of 0.01 μg kg-1 for dieldrin and metoxychlor to 2.00 μg kg-1 for DDT in the Cyprinidae fish family from the Sava River, Zagreb sampling site (group 1).This study has confirmed pesticide persistence in the overall ecosystem in our country despite the ban of some thirty years ago, like in many other parts of the world.

Presence of Dichlorodiphenyltrichloroethane (DDT) in Croatia and Evaluation of Its Genotoxicity

“…The mean value of DDT in fish tissue, analyzed in year 2007, was 3.8 μg/kg wet weights, with median value of 4.7 μg/kg . Similar results are reported by Krautchaker & Reiner (2001), and Bošnir et al (2007). The five dairy products have been examined for the rest of DDT: milk, butter, cheese, cream and yoghurt.…”

Analysis of 16 phthalic acid esters in food simulants from plastic food contact materials by LC‐ESI‐MS/MS

“…Different methods such as GC , GC‐MS , and HPLC had been applied to test the PAEs migration. GC and GC‐MS cannot determine water‐based simulants directly and they need derivatization or extraction.…”

“…GC and GC‐MS cannot determine water‐based simulants directly and they need derivatization or extraction. For example, Bošnir et al had studied six PAEs migrated from plastic containers into soft drinks and mineral water using liquid–liquid extraction coupled with GC method, which was time consuming and hazardous due to the large volume of potentially toxic solvents. Earls et al had developed a GC‐MS method to study six PAEs migrated from polyvinyl chloride toys and childcare articles.…”

Residue of DDT and HCH in Fish from Lakes and Rivers in the World

“…The residue data were summarized in Table 1 for the lakes [22][23][24][25][26][27][28][29][30][31] and in Table 2 for the rivers [40,51,68,. Table 2.…”

“…On the other hand, many field data have been published for temporal monitoring of DDT and HCH in fish from lakes and rivers [40,51,68,.…”
