ikan, air dan sedimen secara beruru

ikan, air dan sedimen secara berurutan adalah endosulfan, DDT, aldrin, dieldrin dan heptaklor.
Sedangkan pada musim kemarau yang paling banyak ditemukan secara berurutan adalah
heptaklor, aldrin, DDT, endosulfan dan dieldrin. Kelima jenis organoklorin ini sama-sama
ditemukan baik pada musim hujan maupun musim kemarau. Hal ini berarti bahwa kemungkinan
besar endosulfan, DDT, aldrin, dieldrin dan heptaklor masih digunakan sebagai pestisida
daerah pertanian DAS Citarum Hulu. Tingkat Pencemaran dan Standar Baku Mutu
Perbandingan tingkat pencemaran organoklorin pada sampel ikan, air dan sedimen ditunjukkan
pada Tabel dibawah ini. Untuk ikan, standar baku mutu yang dipakai adalah Extraneous
Residue Limit (ERL) yang merupakan batas maksimum residu pestisida yang diperbolehkan
yang bersumber dari lingkungan secara langsung/tidak langsung pada suatu komoditi
/makanan. Treshold Effect Level (TEL) digunakan untuk melihat efek buruk pencemaran
organoklorin terhadap sedimen.(Sara,2010)
Penggunaan DDT juga ditemukan disekitar tepian Danau Buyan walaupun kadarnya masih
dibawah ambang yang diperkenankan sekitar 5,02 ppb.(Putra Manuaba,2007). Berdasarkan
hasil pemantauan kadar total pestisida organoklorin yang dilakukan dibeberapa muara sungai
perairan teluk Jakarta kadar pestisida sudah melebihi ambang batas yang diperkenankan untuk
kehidupan biota dengan hasil 51,126 ppb.(Khozanah, 2005). Pada penelitian di sungai Oven
dan King di Australia ternyata ditemukan juga DDE, DDT dan dieldrin pada sampel air dan
sedimennya. (Mc.kenzie smith, 1993)
Pemakaian pupuk dan pestisida dalam jumlah yang besar menimbulkan pencemaran
tanah dan air tanah dengan kadar racun yang beraneka ragam. Degradasi tanah pertanian
sudah makin parah dan dengan sudah mengendapnya pestisida maupun bahan agrokimia
lainnya dalam waktu yang cukup lama. Untuk mengembalikan nutrisinya tanah memerlukan
waktu ratusan tahun, sedangkan untuk merusaknya hanya perlu beberapa tahun saja. Hal ini
terlihat dari menurunnya produktivitas karena hilangnya kemampuan untuk memproduksi
nutrisi.
Apabila penyemprotan dilakukan secara berlebihan atau takaran yang dipakai terlalu
banyak, maka yang akan terjadi adalah kerugian. Tanah disekitar tanaman akan terkena
pencemaran pestisida. Akibatnya makhluk-makhluk kecil itu banyak yang ikut terbasmi,

fish, water and sediment sequence is endosulfan, DDT, aldrin, dieldrin and heptaklor.
While in the dry season most commonly found in a sequence is
heptaklor, aldrin, DDT, endosulfan and dieldrin. The fifth type of organochlorine equally
found in both the rainy season and dry season. This means that the possibility of
large endosulfan, DDT, aldrin, dieldrin and heptaklor still used as a pesticide
agricultural area Citarum Hulu. Pollution Levels and Quality Standards Standards
Comparison of organochlorine contamination levels in fish samples, water and sediment are shown
in the table below. For fish, quality standards used are extraneous
Residue Limit (ERL) which is the maximum allowable pesticide residues
originating from the environment directly / indirectly on a commodity
/ food. Threshold Effect Level (TEL) is used to see the ill effects of pollution
of organochlorines to the sediment. (Sara, 2010)
The use of DDT was also found around the shores of Lake Buyan although the levels are still
below the threshold that allowed approximately 5.02 ppb. (Son Manuaba, 2007). Based on the
results of monitoring of levels of total organochlorine pesticides were conducted in several estuaries
waters of Jakarta Bay pesticide levels already exceed the threshold are allowed to
biota with the results of 51.126 ppb. (Khozanah, 2005). In research on the river Ovens
and King in Australia it was found also DDE, DDT and dieldrin in samples of water and
sediment. (Mc.kenzie smith, 1993)
The use of fertilizers and pesticides in large amounts of polluting
soil and groundwater with toxic levels of diversity. Degradation of agricultural land
has been getting worse and the already mengendapnya pesticides and agrochemicals
other in a long time. To restore soil nutrient require
hundreds of years, while for the damage it just needs a few years. It is
evident from the decrease in productivity due to the loss of the ability to produce
nutrients.
If spraying is done to excess or dose used too
much, then that will happen is a loss. The soil around the plants will be exposed to
pesticide pollution. As a result of these tiny creatures that many who participated eradicated,
