(a) Clarification of the criteria for acute toxicity, reproductive toxicity and target organ systemic toxicity

(k) Toxicity development of a system of rapid monitoring of water toxicity during space flight

3.1.2.5 In footnote 1, replace toxicity class with toxicity Category and Note (e) with Note (f) .

(g) reproductive toxicity (Chapter 3.7). .

3.7.5.1 Decision logic for reproductive toxicity

(a) acute lethality toxicity (Chapter 3.1)

Acute toxicity values are expressed as (approximate) LD50 (oral, dermal) or LC50 (inhalation) values or as acute toxicity estimates (ATE).

The first limitation is the oxygen oxygen toxicity.

He had an oxygen toxicity seizure and he drowned.

In the table for Specific target organ systemic toxicity (single exposure)

Table 3.1.2 In the title, insert for classification after toxicity point estimates .

Chemicals can be allocated to one of five toxicity categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric cut off criteria as shown in the table below.

In the title of the table, replace (approximate) LD50 LC50 with acute toxicity estimates (ATE) .

3.1.2.6.5 In addition to classification for inhalation toxicity, if data are available that indicates that the mechanism of toxicity was corrosivity of the substance or mixture, certain authorities may also choose to label it as corrosive to the respiratory tract.

Did you know rats that ate genetically engineered corn had developed signs of liver and kidney toxicity?

Pursue work to improve further the classification scheme on chronic aquatic toxicity hazards (in cooperation with OECD)

3.8.3.4.5 Care should be exercised when extrapolating toxicity of a mixture that contains Category 3 ingredient(s).

The short answer is They return to the environment in one way or another, continuing the cycle of toxicity.

(a) the acute toxicity estimate (ATE) for the classification of a substance or ingredient in a mixture is derived using

Some reproductive toxic effects cannot be clearly assigned to either impairment of sexual function and fertility or to developmental toxicity.

You die also because oxygen toxicity can cause a seizure makes you convulse underwater, not a good thing to happen underwater.

The work was focused on pathogenicity and toxicity studies, characteristics of agents and methods of their production at the laboratory scale.

In the second sentence of the paragraph, replace specific reproductive toxicity with an adverse effect on sexual function and fertility or on development .

But, if we only had an oxygen gas supply cylinder we wouldn't be able to go very deep, because we'd run into oxygen toxicity very, very quickly.

Generally, the hazard posed to people by a small arms ball round that has been fired and is now lying on the ground is negligible (lead toxicity not included).

James Comer says that no significant learning can occur without a significant relationship.

This is very significant.

They're not statistically significant.

It's significant to us.

There's a significant difference.

Significant cross jurisdictional initiatives

Education may be significant.

The fall of the beryllium reflector parts and partially failed radiation shield of lithium hydride might constitute a threat from the point of toxicity, which would prompt search and clean up (removal) measures.

Furthermore, lower levels of mycotoxins in pest resistant corn mean fewer birth defects, such as spina bifida, and less toxicity to livestock. Such staple food crops also can be modified to contain additional nutrients.

These differences were highly significant.

Do you think that's significant?

There were other significant reactions.

Relative poverty, however, is significant.
