Students can use this worksheet to practice graphing LD-50 data. This is an important skill for the APES exam. Students will also practice dimensional analysis questions using LD-50 numbers. The following list is my take on the 5 most important labs for AP Environmental Science.

Study with Quizlet and memorize flashcards containing terms like Dose Response Studies & LD50, Independent variable =, Dependent variable = and more.

Lethal dose 50% (LD50) is the dose of a chemical that is lethal to 50% of the population of a particular species.

Review Lethal Dose 50% (LD50) for your test on Unit 8 – Aquatic & Terrestrial Pollution. For students taking AP Environmental Science.

Study with Quizlet and memorize flashcards containing terms like line graph, scatter graph, bar graph and more.

LD means Lethal Dose (deadly amount) and the subscript 50 means that the dose was acutely lethal to 50% of the animals to whom the chemical was administered under controlled laboratory conditions.

What does LD50 mean? LD stands for "Lethal Dose". LD50 is the amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 is one way to measure the short-term poisoning potential (acute toxicity) of a material.

The LD-50 of a compound simply means the individual dose of that compound that is required to kill 50% of a population of something. This is calculated in order to assess the risks of certain chemical compounds.

LD-50 is the amount of a toxic agent (as a poison, virus, or radiation) that is sufficient to kill 50 percent of a population of animals usually within a certain time. LD-50 is important because it shows us what level of any chemical/toxin kills 50% of an organism without a 48 hour period.

The LD-50 of a compound is the required amount which when applied results in the death of half of the population. This is used in science as well as many fields in the medical profession. The LD-50 is used to determine how dangerous a product is.
