世界许多资源都可获得硫，但在过去15年中，燃气技术产品公司（简称GTP--Merichem化学炼油服务公司的一个部门）的LO—CAT铁氧化还原技术已成为加利福尼亚州中部农业所需单质硫的主要来源。LO—CAT技术采用铁螯合催化剂，用化学方法将H2S转化为单质硫，从而脱除H2S。这种单质硫的物理性质独特，增强其作为肥料、除藻剂及杀菌剂的功能。加利福尼亚州贝克斯菲尔德的Hondo化学公司15年来一直在推广铁氧化还原法脱硫，该方法的商标为Micro—Sul^TM。

Context: Obesity, diabetes mellitus, and glucose intolerance have been associated with increased pancreatic cancer risk; however, prediagnostic serum insulin concentration has not been evaluated as a predictor of this malignancy. Objective: To investigate whether prediagnostic fasting glucose and insulin concentrations and insulin resistance are associated with subsequent incidence of exocrine pancreatic cancer in a cohort of male smokers. Design, Setting, and Participants: A case-cohort prospective study within the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (1985-1988) cohort of 29 133 male Finnish smokers ages 50 to 69 years. The study included 400 randomly sampled subcohort control participants and 169 incident pancreatic cancer cases that occurred after the fifth year of follow-up. All participants were followed up through December 2001 (up to 16.7 years of follow-up). Main Outcome Measures: Incident exocrine pancreatic cancer identified from the Finnish Cancer Registry. Results: After adjusting for age, smoking, and body mass index, higher baseline fasting serum concentrations of glucose, insulin, and insulin resistance were positively associated with pancreatic cancer. The presence of biochemically defined diabetes mellitus (glucose, ≥ 126 mg/dL ≥ 6.99 mmol/L ) and insulin concentration in the highest vs lowest quartile both showed a significant 2-fold increased risk (hazard ratio HR , 2.13; 95% confidence interval CI , 1.04-4.35; and HR, 2.01; 95% CI, 1.03-3.93; respectively). There were significant interactions for all the biomarker exposures by follow-up time, such that the positive associations were stronger among the cases that occurred more than 10 years after baseline (highest vs lowest quartile: glucose, HR, 2.16; 95% CI, 1.05-4.42; P for trend=.02; insulin, HR, 2.90; 95% CI, 1.22-6.92; P for trend=.005; and insulin resistance, HR, 2.71; 95% CI, 1.19-6.18; P for trend=.006). Conclusions: These results support the hypothesis that exposure t
