Metil karbamat yutulmas\u0131 veya solunmas\u0131 halinde orta derecede toksiktir.<\/span><\/p>\n

Maruziyet sonras\u0131nda bulant\u0131, kusma, ishal ve solunum s\u0131k\u0131nt\u0131s\u0131 gibi belirtiler ortaya \u00e7\u0131kabilir.<\/span><\/p>\n

Uzun s\u00fcreli veya tekrarlanan maruziyet karaci\u011fer ve b\u00f6brek hasar\u0131na da neden olabilir.<\/span><\/p>\n

Metil karbamat ile \u00e7al\u0131\u015f\u0131rken eldiven ve solunum maskesi gibi uygun ki\u015fisel koruyucu ekipman kullan\u0131lmal\u0131d\u0131r.<\/span><\/p>\n

Bu bile\u015fikle \u00e7al\u0131\u015f\u0131rken, maruz kalma riskini en aza indirmek i\u00e7in uygun havaland\u0131rma ve koruyucu \u00f6nlemler al\u0131nmal\u0131d\u0131r.<\/span><\/p>\n

Yak\u0131n akrabas\u0131 olan etil karbamat\u0131n aksine, Salmonella i\u00e7in mutajenik de\u011fildir (Ames testinde negatif) ancak meyve sinekleri i\u00e7in mutajeniktir. Deneysel kan\u0131tlar, s\u0131\u00e7anlarda kanserojen oldu\u011funu ve farelerde kanserojen olmad\u0131\u011f\u0131n\u0131 g\u00f6stermektedir. Proposition 65'e g\u00f6re, bile\u015fik \"Kaliforniya Eyaleti taraf\u0131ndan kanserojen oldu\u011fu bilinmektedir<\/span>.<\/span><\/p>\n

Karbamat pestisit zehirlenmesinin nedenleri di\u011fer pestisit zehirlenmelerine benzer. \u00dcretken zehirlenmeler genellikle pestisitlerin uygun koruyucu \u00f6nlemler al\u0131nmadan veya s\u0131cak ve nemli ortamlarda uyguland\u0131\u011f\u0131nda, \u00f6zellikle deri yoluyla ve solunum yoluyla zehirlenmelerde g\u00f6r\u00fcl\u00fcr. Ya\u015fam zehirlenmesi genellikle intihar veya kaza sonucu zehirlenmelerde, a\u011f\u0131z yoluyla zehirlenmelerde g\u00f6r\u00fcl\u00fcr.<\/span><\/p>\n

Karbamat pestisit zehirlenmesi akuttur, zehirlenmenin ba\u015flang\u0131c\u0131ndan itibaren 10 ila 20 dakika i\u00e7inde oral zehirlenme, 2 ila 6 saat i\u00e7inde zehirlenmenin \u00e7o\u011funlu\u011fu ile temas halinde i\u015f g\u00fcc\u00fc \u00fcretimi ba\u015flar. Organofosforlu pestisit zehirlenmesine benzer \u015fekilde, \u00f6zellikle muskarinik semptomlar daha belirgindir. Hafif zehirlenmelerde hafif muskarinik semptomlar ve ba\u015f d\u00f6nmesi, ba\u015f a\u011fr\u0131s\u0131, yorgunluk, bulant\u0131, kusma, bulan\u0131k g\u00f6rme, t\u00fck\u00fcr\u00fck salg\u0131s\u0131, a\u015f\u0131r\u0131 terleme, g\u00f6z bebe\u011fi daralmas\u0131 gibi merkezi sinir sistemi semptomlar\u0131 g\u00f6r\u00fcl\u00fcr. Yukar\u0131daki semptomlara ek olarak, orta dereceli zehirlenmelerde kas titremesi ve kan bas\u0131nc\u0131nda art\u0131\u015f g\u00f6r\u00fcl\u00fcr. \u015eiddetli zehirlenmelerde akci\u011fer \u00f6demi, koma, beyin \u00f6demi, 30% veya daha d\u00fc\u015f\u00fck tam kan kolinesteraz aktivitesi g\u00f6r\u00fclebilir ve ciddi vakalarda solunum kas felci, solunum yetmezli\u011fi ve hatta \u00f6l\u00fcm g\u00f6r\u00fclebilir. Buna ek olarak, cilt kontaminasyonu yanma, k\u0131zarma, d\u00f6k\u00fcnt\u00fc; konjonktival kontaminasyon yanma hissi, g\u00f6z ya\u015farmas\u0131, g\u00f6z bebe\u011fi daralmas\u0131 ve benzerlerine neden olabilir.<\/span><\/p>\n

Karbamat insektisitlerle zehirlenme \u015f\u00fcphesi derhal tedavi edilmelidir ve kesin tan\u0131, kolinesteraz ve toksikolojik testlerin sonu\u00e7lar\u0131 ile birlikte a\u00e7\u0131k bir maruziyet \u00f6yk\u00fcs\u00fc, semptomlar, belirtiler ve semptomlarla yap\u0131labilir. Bu t\u00fcr zehirlenmeler kan kolinesteraz aktivitesinde azalmaya yol a\u00e7ar, ancak zehirlenmeden sonra m\u00fcmk\u00fcn olan en k\u0131sa s\u00fcrede test edilmelidir ve zehirlenme s\u00fcresi artt\u0131k\u00e7a kolinesteraz aktivitesi kademeli olarak iyile\u015fecektir. Zehir gastrik lavaj vb. y\u00f6ntemlerle uzakla\u015ft\u0131r\u0131l\u0131r ve g\u00fc\u00e7l\u00fc bir antidot olan atropin kullan\u0131l\u0131r. Organofosforlu pestisit zehirlenmelerinin aksine, karbamatl\u0131 insektisit zehirlenmelerinde oksim kolinesteraz reenakt\u00f6rleri yasaklanm\u0131\u015ft\u0131r.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
