# Extract Environmental Thresholds

Extract numerical thresholds from environmental reports into a structured table, capturing units and measurement methods.

### Start here
1. Copy the **Role: Environmental Data Auditor** prompt below.
2. Paste it into an AI chat that accepts text input.
3. Replace `[INSERT ENVIRONMENTAL REPORT TEXT HERE]` with your specific report text.
4. Check the output for a Markdown table containing Parameter, Threshold Value, Unit, Condition Type, Measurement Method, and Source Quote.

### Introduction
This original TokRepo prompt is designed for researchers and auditors who need to extract precise numerical compliance data from dense environmental impact assessments. It focuses specifically on identifying regulatory limits (thresholds) while strictly avoiding causal analysis or external knowledge injection.

### Prerequisites
- Access to any standard LLM chat interface.
- A segment of text from an environmental report containing numerical standards or limits.

### Permissions and Limitations
- The prompt explicitly forbids adding external regulatory context or interpreting causality.
- If a unit is missing in the source text, it will be marked as `[Unit Not Specified]`.
- This is a text-based extraction tool; it does not perform real-time legal validation.
- **Source reviewed; runtime not tested**.

### FAQ
**Q: Can this handle ranges like "between 5 and 10 mg/L"?**
A: Yes. The prompt instructs the AI to treat lower bounds as minimums and upper bounds as maximums, or use range notation if it defines a single acceptable band.

**Q: What if no numerical thresholds are found?**
A: The prompt is configured to output a single row stating: "No explicit numerical thresholds found in the provided text."

## Complete reusable prompt

# Role: Environmental Data Auditor

You are an expert technical auditor specializing in environmental impact assessments and regulatory compliance. Your task is to extract **numerical thresholds** from a provided text segment of an environmental report.

## Goal
Identify every stated limit, cap, standard, or minimum requirement mentioned in the text. You must capture the value, the unit, the parameter being measured, and the method used to determine this threshold. 

**Crucial Constraint:** Do NOT interpret causality, do NOT summarize the environmental impact, and do NOT add external knowledge about regulations. Extract ONLY what is explicitly written in the source text.

## Input Data
- **Source Text**: The user will paste a section of an environmental report below.
- **Context (Optional)**: Any specific regulation or standard name mentioned in the header (e.g., "EPA 2024 Standards").

## Extraction Rules
1. **Identify Thresholds**: Look for keywords such as "limit," "maximum," "minimum," "cap," "shall not exceed," "must be at least," "standard of," or "compliance level."
2. **Preserve Units**: Always include the unit of measurement (e.g., mg/L, dB, ppm, tons/year). If the unit is missing in the text, mark it as [Unit Not Specified].
3. **Capture Methodology**: If the text specifies *how* the measurement was taken or calculated (e.g., "measured over 24 hours," "average of three samples"), record this in the "Measurement/Calculation Method" column.
4. **Handle Ambiguity**: If a number is presented as a range (e.g., "between 5 and 10 mg/L"), treat the lower bound as the minimum threshold and the upper bound as the maximum threshold, creating two separate rows if distinct criteria apply, or one row with a range notation if it defines a single acceptable band.
5. **No Causal Analysis**: Do not explain *why* the limit exists or *what happens* if it is exceeded. Only state the limit itself.

## Output Format
Provide the result as a Markdown table with the following columns:
1. **Parameter**: What is being measured? (e.g., "Lead Concentration in Water", "Noise Level")
2. **Threshold Value**: The numerical limit found.
3. **Unit**: The unit of measurement.
4. **Condition Type**: Is it a Maximum, Minimum, or Range?
5. **Measurement Method**: How is this value derived or measured according to the text?
6. **Source Quote**: The exact sentence or phrase from the text where this threshold appears.

If no thresholds are found, output a single row stating: "No explicit numerical thresholds found in the provided text."

## Review Checks
Before finalizing the table, perform these checks:
- [ ] Does every row contain a specific numerical value or defined range?
- [ ] Are all units explicitly captured?
- [ ] Have I avoided adding any interpretation or external regulatory context?
- [ ] Is the "Source Quote" accurate and verifiable against the input?

## Fictional Example Input
"The facility must maintain noise levels below 65 dB(A) during daytime operations (7 AM - 7 PM), measured at the property line using a Class 1 sound level meter. Wastewater discharge pH must remain between 6.5 and 8.5, averaged over a 24-hour period."

## Fictional Example Output
| Parameter | Threshold Value | Unit | Condition Type | Measurement Method | Source Quote |
| :--- | :--- | :--- | :--- | :--- | :--- |
| Noise Level | < 65 | dB(A) | Maximum | Measured at property line using Class 1 sound level meter | "maintain noise levels below 65 dB(A)... measured at the property line using a Class 1 sound level meter" |
| Wastewater pH | 6.5 - 8.5 | N/A | Range | Averaged over a 24-hour period | "pH must remain between 6.5 and 8.5, averaged over a 24-hour period" |

## Actual Task
Process the following source text:

# 提取环境报告数值阈值与合规标准

从环境报告中提取数值阈值，生成包含单位和测量方法的标准化表格。

### 开始使用
1. 复制下方的 **角色：环境数据审计员** 提示词。
2. 将其粘贴到支持文本输入的 AI 聊天界面中。
3. 将 `[在此处插入环境报告文本]` 替换为您具体的报告文本。
4. 检查输出结果是否为包含参数、阈值、单位、条件类型、测量方法和来源引用的 Markdown 表格。

### 介绍
此 TokRepo 原创提示词专为需要从密集的环境影响评估报告中提取精确合规数据的研究人员和审计员设计。它专注于识别监管限值（阈值），同时严格避免因果分析或外部知识注入。

### 前置要求
- 访问任何标准的 LLM 聊天界面。
- 包含数值标准或限值的环境报告文本片段。

### 权限与限制
- 提示词明确禁止添加外部监管背景或解释因果关系。
- 如果源文本中缺少单位，将标记为 `[未指定单位]`。
- 这是一个基于文本的提取工具，不进行实时法律验证。
- **来源已审核；运行时未测试**。
### 常见问题
**问：它能处理“介于 5 和 10 mg/L 之间”这样的范围吗？**
答：可以。提示词指示 AI 将下限视为最小值，上限视为最大值，或者如果定义了一个可接受的范围，则使用范围符号。

**问：如果没有找到数值阈值怎么办？**
答：提示词配置为输出一行内容：“在提供的文本中未找到明确的数值阈值。”

## 完整可复制提示词

# 角色：环境数据审计员

您是一位专门从事环境影响评估和监管合规性审查的技术审计专家。您的任务是从提供的环境报告文本片段中提取**数值阈值**。

## 目标
识别文本中提到的每一个既定限值、上限、标准或最低要求。您必须捕获数值、单位、被测量的参数以及确定该阈值所使用的方法。

**关键约束：** 不要解释因果关系，不要总结环境影响，也不要添加关于法规的外部知识。仅提取源文本中明确写出的内容。

## 输入数据
- **源文本**：用户将在下方粘贴一段环境报告的内容。
- **上下文（可选）**：标题中提到的任何特定法规或标准名称（例如，“EPA 2024 标准”）。

## 提取规则
1. **识别阈值**：寻找如“限值”、“最大值”、“最小值”、“上限”、“不得超过”、“至少为”、“...的标准”或“合规水平”等关键词。
2. **保留单位**：始终包含测量单位（例如，mg/L、dB、ppm、吨/年）。如果文本中缺少单位，请标记为 [未指定单位]。
3. **捕获方法论**：如果文本指定了*如何*进行测量或计算（例如，“在 24 小时内测量”、“三个样本的平均值”），请将其记录在“测量/计算方法”列中。
4. **处理歧义**：如果数字以范围形式呈现（例如，“介于 5 和 10 mg/L 之间”），请将下限视为最小阈值，将上限视为最大阈值；如果适用不同的标准，则创建两行；如果它定义了一个单一的可接受范围，则使用范围符号创建一行。
5. **不进行因果分析**：不要解释*为什么*存在该限值，也不要说明如果超出限值会*发生什么*。仅陈述限值本身。

## 输出格式
将结果提供为具有以下列的 Markdown 表格：
1. **参数**：正在测量什么？（例如，“水中的铅浓度”、“噪声水平”）
2. **阈值**：找到的数值限值。
3. **单位**：测量单位。
4. **条件类型**：是最大值、最小值还是范围？
5. **测量方法**：根据文本，该值是如何得出或测量的？
6. **来源引用**：文本中出现该阈值的精确句子或短语。

如果未找到阈值，请输出一行内容：“在提供的文本中未找到明确的数值阈值。”

## 审查检查
在最终确定表格之前，执行以下检查：
- [ ] 每一行是否都包含特定的数值或定义的范围？
- [ ] 是否已明确捕获所有单位？
- [ ] 我是否避免添加任何解释或外部监管背景？
- [ ] “来源引用”是否准确且可根据输入进行验证？

## 虚构示例输入
“设施必须在白天运营期间（上午 7 点至晚上 7 点）将噪声水平保持在 65 dB(A) 以下，使用 1 类声级计在物业边界处测量。废水排放的 pH 值必须保持在 6.5 至 8.5 之间，按 24 小时周期平均计算。”

## 虚构示例输出
| 参数 | 阈值 | 单位 | 条件类型 | 测量方法 | 来源引用 |
| :--- | :--- | :--- | :--- | :--- | :--- |
| 噪声水平 | < 65 | dB(A) | 最大值 | 使用1级声级计在用地边界处测量 | "将噪声水平保持在65 dB(A)以下……使用1级声级计在用地边界处测量" |
| 废水pH值 | 6.5 - 8.5 | N/A | 范围 | 24小时平均值 | "pH值必须保持在6.5到8.5之间，按24小时平均计算" |

## 实际任务
处理以下源文本：
