Residu insektisida organoklor (lindan, aldrin, dieldrin, heptaklor dan
endosulfan) dan organofosfat (klorpirifos, propenofos, diazinon dan malation)
telah diteliti terhadap sampel tanah, air, beras darl enam desa di Karawang
dan produk olahan beras darl dua belas pasar tradisional di Karawang,
Jakarta dan Bogor. Metode analisis residu insektisida berdasarkan pada
kromatografi gas-cair dengan' detektor penangkap eiektron. Dari total
sembilan jenis insektisida yang diuji, seluruhnya terdeteksi pada sampel
dengan konsentrasi berkisat dari tak terdeteksi sampai 101,2 ng/g.
Frekuensi deteksi residu berkisar dari 3,1% (3 sampel) sampai 86 % (84
sampel). Lindan merupakan yang paling banyak terdeteksi diikuti klorpirifos
(52,0 %; 51 sampel) dan aldrin (51,0 %; 50 sampel). Sebanyak 15,71 % (11
sampel) produk beras yang berasal dari Bogor yaitu jenis nasi (2 sampel),
bubur (1 sampel) buras (2 sampel), lemper (2 sampel), ketupat (1 sampel)
dan lontong (3 sampel) tercemar aldrin melebihi batas maksimum residu yang
dihitung dari AD! {Acceptable Daily Intake). Nilai ED! {Estimated Daily Intake)
buras, lemper dan lontong berturut-turut 23,52 xlO"^; 12,44x10"^; dan
15,35x10"^ mg/kg berat badan per hari dengan pencapaian AD I berturut-turut
235,2; 124,4 dan 153,5 % sehingga beresiko terhadap kesehatan konsumen.
Konsumsi maksimal produk beras ini yang masih aman adalah 2 buras, 4
lemper dan 192,99 miligram lontong. Sedangkan sampel tanah, air, beras
dan produk beras lainnya masih aman
The residue levels of organochiorine insecticides (iindane, aldrin,dieldrin, heptachlor and endosulfan) and organophosphorus insecticides(chlorpyriphos, propenofos, diazinon and malathion) were determined in soil,water and rice from six villages in Karawang and rice products from twelvetraditional markets around Karawang, Jakarta and Bogor. The method formonitoring these residues based on gas-liquid chromatography with electroncapture detector. All of the nine organochiorine and organophosphorusinsecticides investigated, were detected at concentration ranging from nondetectableto 101,2 nanogram/gram. Frequencies of detection of insecticidesresidues ranged from 3,1 % (3 samples) to 86 %(84 samples). Lindane wasthe most frequently detected followed by chlorpyriphos (52,0 %; 51 samples)and aldrin (51,0 %, 50 samples). A total of 15,71 % (11 samples) riceproducts from Bogor such as rice (2 samples), bubur (1 sample), buras (2samples), lemper (2 samples), ketupat (1 sample) and lontong (3 samples)contained aldrin exceeded Maximum Residue Limits (MRLs) determined fromAcceptable Daily Intake. The EDIs (Estimated Daily Intakes) of aldrin forburas, lemper, and lontong were 23, 52x10"®; 12,44x10"®; 15,35x10"® mg/kgbody weight/day, respectively. These EDIs have exceeded ADI, were 235,2% (buras), 124,4 % (lemper); 153,5 % (lontong). Therefore, consumption ofthese foods poses a risk to consumer health. Based on ADI achieved,maximum rice products consumption that will not pose a risk to consumerhealth for buras, lemper and lontong are 2, 4 and 192,99 miligram,respectively. The rest samples such as water, soil, rice and other riceproducts were in safe level.
