Potential health effects

Inhalation: Acute (short term) exposure to dust levels exceeding the PEL may cause irritation of respiratory tract resulting in a dry cough. Chronic (long term) exposure to airborne Bentonite dust containing respirable size quartz particles, here respirable q�ar�� paricle leels are higher han TLVs, may lead to development of silicosis or other respiratory problems. Persistent dry cough and labored breathing upon exertion may be symptomatic. 2. HAZARD IDENTIFICATION (cont.) Permissible Exposure OSHA PEL ACGIH TLV Limits: (8 hour TWA) Ben�oni�e as �Par�icles no o�her�ise reg�la�ed� (Formally nuisance dust) Total dust: 15 mg/m3 ND Respirable dust: 5 mg/m3 ND Crystalline Silica: Quartz (Respirable) 10 mg/m3 0.025 mg/m3 % Silica +2 Carcinogenicity: Bentonite is not listed by ACGIH, IARC, NTP, or OSHA. IARC, 1997, concludes that there is sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica from occupational sources (IARC Class 1), that carcinogenicity was not detected in all industrial circumstances studied and that carcinogenicity may depend on characteristics of the crystalline silica or on external factors affecting its biological activity. NTP classifies respirable cr�s�alline silica as �kno�n o be a hman carcinogen (NTP 9th Report on Carcinogens - 2000). ACGIH classifies crystalline silica, quartz, as a suspected human carcinogen (A2).
