The<br \/>\ndata were collected and estimated as a part of a project studying the regional cycling of persistent organic pollutants (POPs) in the Baltic environment (Popcycling-Baltic). Better data on sources, environmental discharges and atmospheric emissions of HCH and other POPs are needed to study, and hopefully reduce, the impact of these<br \/>\npollutants on the environment. Substantial uncertainties are assigned to the estimated data for individual countries<br \/>\nand years, but it seems likely that the general trend of usage in Europe is captured. The quality of the estimates is<br \/>\nthought to improve in general throughout the period, thus, reflecting the availability of reliable data. The results<br \/>\nsuggest that 382 000 t of technical HCH and 81 000 t of lindane were used in Europe from 1970 to 1996. This is<br \/>\nequivalent to an estimated cumulative usage of 259 000 t a-HCH, 135 000 t g-HCH and 20 000 t b-HCH. The usage<br \/>\nof technical HCH was the major source of g-HCH until the late 1970s, and thereafter lindane became the<br \/>\ndominating source of this isomer. The use of g-HCH in 1996 was estimated to still be nearly one-third of the<br \/>\nEuropean usage in 1970. The pattern of decreasing concentrations in biota follows the pattern of reductions in usage for the studied period within the Baltic area.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 13:53:14","footnotes":""},"nva_tax_category":[1099],"class_list":["post-113962","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-scientific-journal-publication"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/113962","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/113962\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=113962"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=113962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
