Toxicokinetics
The toxicokinetics of 3-chloroaniline have been investigated on dermal and basic toxicokinetics studies. Following oral administration and intra-arterial in fusion, 3-chloroaniline is found to be rapidly absorbed and is excreted predominantly in the urine. Based on the study reported it indicates that there is no potential for bioaccumulation.
Acute toxicity
3-chloroaniline is of moderately acute toxicity by all routes investigated, the acute oral LD50 of the substance was found to be 256 mg/kg/bw on the mouse (V/O Mezhdunarodnaya Kniga); the acute dermal also show LD50 value as 250 mg/kg (Woo,Y.-T.,et al.). The acute inhalation toxicity also shows the LD50 value in the range 550 mg/kg (Woo,Y.-T.,et al.).
Irritation / corrosion
In vivo studies of the substance show that the substance is a non - irritating to skin and also do not have irritation effect to eyes, and so the substance is not classified in skin irritation category and also no eye irritation according to current criteria.
Sensitisation
No evidence of skin sensitisation was noted in a estimation study for the substance.

DNEL derivation
3-chloroaniline is of moderate acute toxic to oral, dermal and inhalation, is not irritant to skin and eye, is not genotoxic and is not a developmental or reproductive toxin.
In the absence of local effects following short-term or long-term exposure, no dose-response data are available and a quantitative dose descriptor is not derived. DNEL values for local exposure are therefore not calculated.
In the absence of acute systemic toxicity, no dose-response data are available and a quantitative dose descriptor is not derived. DNEL values for acute systemic effects are therefore not calculated.
A standard approach to deriving DNEL values would be to use the repeated dose toxicity dataset and apply assessment factors as described in ECHA guidance documents. The critical endpoint is considered to be the NOAEL of 25 mg/kg bw/d in oral category.
