Pafupifupi miyezi isanu ndi iwiri yapitayo - Marichi 3, 2020 - kunena zowona, anthu mazana atatu okhudzidwa adadzaza mulaibulale ya Lexington Park kuti amve Navy ikuteteza kugwiritsa ntchito mankhwala a peroro and poly fluoroalkyl (PFAS) ku Patuxent River Naval Air Station ( Pax River) ndi Webster Outlying Field.
Anthu anali ndi nkhawa chifukwa ndinali nditangotulutsa kumene zotsatira zoyesa akuwonetsa milingo ya zakuthambo ya poizoni ku St. Inigoes Creek, kumusi kuno ku St. Mary's County, pamtunda wa 2,400 chabe kuchokera ku Webster Field komwe zinthuzo zimagwiritsidwa ntchito mozungulira kwa zaka zambiri.
Nthawi yomweyo ndinagawana zotsatira zanga ndi Dipatimenti Yachilengedwe ya Maryland (MDE), ndipo ndinalandila yankho kuchokera kwa wolankhulira. "Dipatimenti Yachilengedwe ya Maryland ilibe upangiri pakadali pano wokhudzana ndi zoopsa. Malo okhawo odziwika a PFAS amakhala ndi madzi akumwa, pomwe chiopsezo chazowonekera kwambiri. ”
Kuyankha kwa MDE kukuwonetsa kusachita kwa boma ndikunena molakwika kuti kufalikira kwa PFAS ndikofunikira kwambiri m'madzi akumwa. Mbali zambiri za PFAS m'matupi mwathu ndizogwiritsa ntchito nsomba zam'madzi zoipitsidwa. Navy ndi MDE onse amamvetsetsa izi. Ndikosavuta kuti boma lizifunsa izi chifukwa zakumwa zakumwa zakumatauni zimatha kuthandizidwa. Kuthana ndi kuipitsidwa kwa asitikali amisewu yosalimba yaboma ndi nkhani ina. Awa ndi "mankhwala kwanthawizonse" ndipo amakhala mozungulira kwa nthawi yayitali, ngati theka la moyo wazinthu zopangira ma radio.
Msonkhanowu utangotha kumene, komwe kunadzetsa ngozi zankhondo kwa Navy ndi omwe amathandizira, MDE, boma linayambitsa kafukufuku woyendetsa ndege kuti awone kuchuluka kwa kuipitsidwa kwa PFAS m'madzi apamtunda ndi oyisitara pafupi ndi Pax River ndi Webster Field. MDE yalengeza kuti zotsatirazo zikhala zokonzeka pofika pakati pa Meyi.
Zotsatira zili kuti, Maryland?
Per fluoro octane sulfonic acid (PFOS) adapezeka pagombe langa magawo 1,544 pa trilioni. (ppt.) PFOS ndi mitundu yoopsa kwambiri yamankhwala onse a PFAS ndipo ndiyabwino kwambiri kuphatikizira, zomwe zikutanthauza kuti zimamangirira - ndipo sizimaphwanyaphwanya nkhanu, oyster, ndi nsomba zomwe a Marylanders amadya pafupipafupi.
Kutengera zotsatira zanga ndi zotsatira za nsomba mazana ndi magulu omwe ali nawo a PFOS m'mitsinje mdziko lonselo, Maryland ili ndi ma oyster omwe amakhala ndi magawo zikwizikwi pa triliyoni za PFOS pomwe oyang'anira mabungwe azaumoyo mdziko muno akutichenjeza kuti tisadye 1 ppt patsiku la izi poizoni zomwe zimalumikizidwa ndi khansa zingapo komanso zovuta za fetus.
Kubwerera mu Marichi, Ira May, yemwe amayang'anira kuyeretsa malo ku MDE, adafunsa ngati pali kuipitsidwa kulikonse ku St. Inigoes Creek kutengera zotsatira zomwe ndidapeza. Ngati mankhwalawa adalipo, adati akadachokera ku dipatimenti yozimitsa moto. Malo ozimitsira moto ku Valley Lee ndi Ridge ali pamtunda wamakilomita pafupifupi asanu. Mkulu wapamwamba m'boma akukwirira zankhondo.
Tikudikirira zotsatira. MDE yatulutsa mawu okhumudwitsa awa okhudzana ndi kuipitsidwa kwa PFAS:
“Ogwiritsa ntchito ayenera kukumbukira kuti kuopsa kogwiritsa ntchito nsomba ndi nkhono zomwe zimagulitsidwa nthawi zambiri kumakhala kocheperako poyerekeza ndi nsomba ndi nkhono. Izi ndichifukwa choti ogula omwe amagula nsomba ndi nkhono za nkhono kwa wogulitsa yemwe ali ndi mbiri yabwino sakupeza nsomba kapena nkhono zofiirira pamalo omwewo sabata iliyonse kapena mwezi uliwonse. ”
Iyi ndi mfundo yaboma yoipa. Sungani kapena tsekani, Maryland. Zotsatira zili kuti?
