最近在申请一个工作Offer，贝壳，一个新产品的技术主管。。
主要是负责一种产品在国内的技术推广....可惜我是学工程技术的，对于化学品真的不太懂。。。

SULPHUR EXTENDED ASPHALT MODIFIER
这个东西我做过试验，基本上不带防毒面具会把自己熏死....怀疑有毒，可惜没有证明。。。。

现在查到一些毒性资料不太清楚，想问问知道的人
HAZARDS IDENTIFICATION
Hazards: An ingredient in this product has been classified by IARC as possibly carcinogenic to humans (Group 2B). 2B是那种危险程度哦？有类似的东西不？最好熟悉的

TOXICOLOGICAL INFORMATION
Ingredient (or Product if not specified) Toxicological Data：
Carbon Black LD50 Dermal Rabbit > 3000 mg/kg
LD50 Oral Rat > 15400 mg/kg
这个是什么意思哦？

Routes of Exposure: Exposure to this product in pastille or pellet form is expected to be low by all
routes. However, in the handling of the product, dust may be generated and exposure may then occur through inhalation, skin and eye contact or ingestion
Formulation: No data is specifically available for this product and therefore this toxicological information is based on data available for the ingredients.
Irritancy: This product is not a primary skin irritant after exposure of short duration, is not a skin sensitizer and is not irritating to the eyes.
Chronic Effects: Carbon black has been shown to cause lung fibrosis and other similar effects in
production workers following long-term (>10 years) exposure.
Pre-existing
Conditions: Pre-existing eye, skin and respiratory disorders may be aggravated by exposure to this product.
Carcinogenicity and Mutagenicity:
This product contains carbon black. Rats that inhaled carbon black particles developed an increased incidence of respiratory tract tumours. These tumours are likely the result of a high pulmonary overload which is of questionable relevance in humans. Benzene extracts of carbon black resulted in skin tumours when painted on the skin of mice。

REGULATORY INFORMATION：
WHMIS Class: Class D2A Carcinogenicity
DSL/NDSL Status: This product, or all components, are listed on the Domestic Substances
List, as required under the Canadian Environmental Protection Act. This
product and/or all components are listed on the U.S. EPA TSCA Inventory.
这个产品对于环境是否有严重的破坏作用？
国内是否能使用这种毒性的产品在交通基础设施建设上，例如公路，市政道路之类

谢谢
