Chromium content in fish and rice and its effect on public health along the downstream Opak River, Bantul District, Indonesia

Abstract. Rahardjo D, Djumanto, Prasetyaningsih A, Laoli B, Manusiwa WS. 2021. Chromium content in fish and rice its effect on public health along the downstream Opak River, Bantul District, Indonesia. Intl J Bonorowo Wetlands 11: 69-74. The activities of leather home industry are overgrowing, causing liquid waste flowing into river also to increase so that threat ecosystem water users increases. This study aimed determine concentration chromium environmental components, agricultural commodities, fisheries, risk health. Sampling was carried out from February August 2020 irrigation canals fields using River flow. number sampling locations is determined at six stations. At each station, samples water, sediment samples, fish, were collected. All analyzed Atomic Absorption Spectrophotometry (AAS). results showed metal found solid or mineral compounds with other elements. highest plants an average 1.0105-6.2870 mg/kg, followed by (1.2062 mg/kg), sediments (0.7126), (0.3799-0.8489), (0.2393 mg/L), lowest (0.0188 mg/L). Tolerable Maximum Intake tilapia meat 3.0271 kg/week, Spotted barb 1.3546 kg/week. daily intake ranged 18.475 28.733 (mg/kg BW/day). Hazard quotient (HQ) level consumption chromium-contaminated 4.618-7.183. HQ value all research sites exceeds safe for set World Health Organization (WHO), namely HQ<1.
